Question : The pie chart given below shows the sales of 7 different companies. The total sales of all these 7 companies is 2160. The sale of a particular company is shown in terms of degree with respect to the total sales of all these 7 companies. The total sales of P, R, and S are how much percentage less than the total sales of Q, T, and U?
Option 1: 56.42%
Option 2: 24.42%
Option 3: 46.53%
Option 4: 32.32%
Correct Answer: 46.53%
Solution : Total sales of P, R, and S in terms of degrees $=26^\circ + 12^\circ + 70^\circ = 108^\circ$ Total sales of Q, T, and U in terms of degrees $=150^\circ + 37^\circ + 15^\circ = 202^\circ$ The sale of a company is proportional to the
Question : If $\triangle \mathrm{ABC}$ is right angled at $B, A B = 12 \mathrm{~cm},$ and $\angle \mathrm{CAB} = 60^{\circ}$, determine the length of BC.
Option 1: $12 \sqrt{2} \mathrm{~cm}$
Option 2: $12\mathrm{~cm}$
Option 3: $12 \sqrt{3} \mathrm{~cm}$
Option 4: $24 \sqrt{3} \mathrm{~cm}$
Correct Answer: $12 \sqrt{3} \mathrm{~cm}$
Solution : Given: AB = 12 cm AC is the hypotenuse of the triangle. We have to find tan of $\angle CAB = \tan 60° = \frac{\text{BC}}{\text{AB}}$ $⇒\sqrt{3} = \frac{\text{BC}}{12}$ $\therefore\text{BC} = 12\sqrt{3}\mathrm{~cm}$ Hence, the correct answer is $12\sqrt{3}\mathrm{~cm}$.
Question : Food crops comprise.
Option 1: Cotton, Tobacco, Sugarcane
Option 2: Linseed, Castor, Turmeric
Option 3: Foodgrains, Pulses, Edible oilseed
Option 4: Jute, Cotton, Chillies
Correct Answer: Foodgrains, Pulses, Edible oilseed
Solution : The correct answer is Foodgrains, Pulses, Edible oilseed.
Crops are classified based upon their utility into two types- Food crops and Cash crops. Food crops are the one which are produced for consumption by the farmers and form the main portion of
Question : Dharmendra can row 80 km upstream and 110 km downstream in 13 hours. Also, he can row 60 km upstream and 88 km downstream in 10 hours. What is the speed (in km/hr ) of the current?
Option 1: 6
Option 2: 16
Option 3: 10
Option 4: 12
Correct Answer: 6
Solution : Let downstream speed and upstream speeds be $u$ km/hr and $v$ km/hr, respectively. Dharmendra can row 80 km upstream and 110 km downstream in 13 hours $\frac{110}{u}+\frac{80}{v}=13$..................(I) He can row 60 km upstream and 88 km downstream in 10 hours. $\frac{88}{u}+\frac{60}{v}=10$..................(II) Equation (I) is multiplied
Question : In organic chemistry, which of the following is an empirical rule used to predict the regioselectivity of electrophilic addition reactions of alkanes and alkynes?
Option 1: Cornforth’s rule
Option 2: Bredt’s rule
Option 3: Markovnikov’s rule
Option 4: Baldwin’s rule
Correct Answer: Markovnikov’s rule
Solution : The correct answer is Markovnikov’s rule.
Certain chemical addition reactions can be described by Markovnikov's rule, commonly referred to as Markovnikov's rule. As per this rule, the carbon (C) atom with fewer hydrogen atoms is bound by the nucleophilic X-, whereas the carbon
Question : If in acute-angled triangle ABC, AL, BM, and CN are the three altitudes of triangle ABC, then which of the following statements will be true?
Option 1: AL + BM + CN = AB + BC + CA
Option 2: AL + BM = AB + BC
Option 3: AL + BM + CN > AB + BC + CA
Option 4: AL + BM + CN < AB + BC + CA
Correct Answer: AL + BM + CN < AB + BC + CA
Solution :
We know the theorem states that the sum of three altitudes of a triangle is less than the sum of three sides of the triangle. The altitudes form right angles with the opposite sides of
Question : Directions: Which two signs should be interchanged to make the given equation correct? 912 – 456 × 28 + 390 ÷ 2 = 444
Option 1: ÷ and –
Option 2: ÷ and +
Option 3: – and +
Option 4: + and ×
Correct Answer: ÷ and –
Solution : Given: 912 – 456 × 28 + 390 ÷ 2 = 444
Replace the given symbols in the options one by one with the original symbols in the given equation and apply the BODMAS rule. First option: ÷ and – = 912 ÷
Question : The soil conservation method in which mountain slope is cut into step is
Option 1: Contour ploughing
Option 2: Cover planting
Option 3: Strip cropping
Option 4: Terracing
Correct Answer: Terracing
Solution : The correct option is Terracing.
Terracing, a land management strategy that involves the development of level or slightly sloping platforms on steep terrain, has numerous significant advantages. By reducing water flow and conserving important topsoil, it effectively reduces soil erosion. These flat or moderately sloping
Question : Ozone protects biosphere from:
Option 1: X -rays
Option 2: Gamma rays
Option 3: Ultraviolet rays
Option 4: Infrared rays
Correct Answer: Ultraviolet rays
Solution : The correct option is Ultraviolet rays.
Ozone is critical in safeguarding the biosphere from the sun's damaging ultraviolet (UV) radiation. Ozone molecules have a unique ability to absorb and block a considerable fraction of incoming UV light, particularly UV-C and UV-B photons with shorter
