Question : A sum is deposited in a bank which gives simple interest. The sum becomes 1.25 times in 3 years. If there is a requirement of INR 7,60,000 after seven years, how much amount (in INR) should one deposit to fulfil the requirement?
Option 1: 5,20,000
Option 2: 5,70,000
Option 3: 4,80,000
Option 4: 6,00,000
Correct Answer: 4,80,000
Solution : The sum becomes 1.25 times in 3 years Let the deposit be $P$ ⇒ Interest earned $= 1.25P - P = 0.25P$ According to the formula Simple interest $=\frac{P\times r\times t}{100}$ ⇒ $0.25P =\frac{P\times r ×3}{100}$ ⇒ $r=\frac{100\times 0.25P}{P\times3}$ ⇒ $r = \frac{25}{3}$% There is

Question : The length of the side of a cube is 5.6 cm. What is the volume of the largest sphere that can be taken out of the cube?
Option 1: 91.98 cm3
Option 2: 99.96 cm3
Option 3: 96.98 cm3
Option 4: 90.69 cm3
Correct Answer: 91.98 cm3
Solution : Diameter of the sphere $=$ Edge of the cube ⇒ $2 ×$ radius of sphere $= 5.6$ cm ⇒ The radius of sphere, $r$ $= \frac{5.6}{2} = 2.8$ cm The volume of the sphere $= \frac{4}{3} × π × r^3$ $=\frac{88}{21} × 21.952=91.98$
Question : Directions: In the following question a series is given, with one number missing. Choose the correct alternative from the given ones that will complete the series. 8, 24, 12, ?, 18, 54
Option 1: 48
Option 2: 36
Option 3: 29
Option 4: 21
Correct Answer: 36
Solution : Given: 8, 24, 12, ?, 18, 54
Multiply by 3 and divide by 2 alternatively to get the next term of the series – 8 × 3 = 24; 24 ÷ 2 = 12; 12 × 3 = 36; 36 ÷ 2 = 18; 18
Question : A man can row 10 km/hr in still water. When the river is running at a speed of 4.5 km/hr, then it takes him 2 hours to row to a place and comes back to the initial point. How far is the place (in km) (rounded off to two decimal places)?
Option 1: 5.50
Option 2: 8.98
Option 3: 7.98
Option 4: 6.25
Correct Answer: 7.98
Solution : Downstream speed = (10 + 4.5) = 14.5 km/hr Upstream speed = (10 – 4.5) = 5.5 km/hr Let the distance be $x$ km. According to the question, $\frac{x}{14.5}+\frac{x}{5.5}=2$ ⇒ $\frac{10x}{145}+\frac{10x}{55}=2$ ⇒ $550x+1450x=2×145×55$ ⇒ $2000x=2×145×55$ ⇒ $x=\frac{2×145×55}{2000}$ ⇒ $x= 7.975 \approx 7.98$ km Hence, the
