Question : What is the value of 28 × 25 ÷ 7 × 15 + 63 × 56 ÷ 72 × 5 + 24 × 7 + 8?
Option 1: 2101
Option 2: 1821
Option 3: 1921
Option 4: 1901
Correct Answer: 1921
Solution : $28 × 25 ÷ 7 × 15 + 63 × 56 ÷ 72 × 5 + 24 × 7 + 8$ $= 28 × \frac{25}{7} × 15 + 63 × \frac{56}{72} × 5 + 24 × 7 + 8$ $=1500+245+168+8$ $=1921$ Hence, the correct answer

Question : Directions: Which of the following numbers will replace the question mark (?) in the given series? 77, 78, 74, 83, 67, ?
Option 1: 188
Option 2: 88
Option 3: 92
Option 4: 192
Correct Answer: 92
Solution : Given: 77, 78, 74, 83, 67, ?
Follow the pattern to obtain the required number –
So, 92 is the required number in the given series. Hence, the third option is correct.
Question : Directions: Read the given statements and conclusions carefully. Assuming that the information given in the statements is true, even if it appears to be at variance with commonly known facts, decide which of the given conclusions logically follow(s) from the statements. Statements: All scales are pencils. Some pencils are erasers. Conclusions: I. Some scales are erasers. II. Some pencils are scales.
Option 1: Both I and II follow
Option 2: Only II follows
Option 3: Only I follows
Option 4: Neither I nor II follows
Correct Answer: Only II follows
Solution : The possible Venn diagram according to the given statements is as follows – Let's analyse the conclusions – Conclusion I: Some scales are erasers – From the Venn diagram, it is evident that there is no definite relation between scales and erasers. Thus,
Question : If $a+b+c = 0$, then the value of $\small \frac{1}{(a+b)(b+c)}+\frac{1}{(b+c)(c+a)}+\frac{1}{(c+a)(a+b)}$ is:
Option 1: 0
Option 2: 1
Option 3: 3
Option 4: 2
Correct Answer: 0
Solution : Given: $a+b+c = 0$ Solution: $\frac{1}{(a+b)(b+c)}+\frac{1}{(b+c)(c+a)}+\frac{1}{(c+a)(a+b)}$ Taking the LCM, we get = $\frac{(c+a)+(a+b)+(b+c)}{(a+b)(b+c)(c+a)}$ = $\frac{2(a+b+c)}{(a+b)(b+c)(c+a)}$ Substituting the value of $(a+b+c)$ in the equation: = $\frac{2\times 0}{(a+b)(b+c)(c+a)}$ = 0 Hence, the correct answer is 0.
Question : Find the smallest number which when divided by 19 and 23 gives remainders of 13 and 17 respectively.
Option 1: 419
Option 2: 429
Option 3: 431
Option 4: 437
Correct Answer: 431
Solution : The difference between divisor and remainder, i) 19 – 13 = 6 ii) 23 – 17 = 6 The difference between the divisor and remainder is the same. The LCM of 19 and 23 is 437. To get the smallest number, which gives the remainder
Question : Directions: A farmer is preparing his field. He starts his tractor from the garage and drives 5 km towards the East. From there, he turns right and drives 6 km. Then, he turns right and drives 8 km. Again, he turns right and drives 10 km when his tractor breaks down. What is the shortest distance between his current location and the garage?
Option 1: 5 km
Option 2: 6 km
Option 3: 9 km
Option 4: 2 km
Correct Answer: 5 km
Solution : Firstly, we will draw the diagram as per the given instructions –
Now, we have to find the shortest distance between his current location and the garage.
EF = ED – FD (FD = BC) EF = 10 – 6 EF = 4 km
Question : In a water-lifting electric pump, we convert
Option 1: electrical energy into potential energy
Option 2: kinetic energy into electrical energy
Option 3: kinetic energy into potential energy
Option 4: electrical energy into kinetic energy
Correct Answer: electrical energy into potential energy
Solution : The correct option is electrical energy into potential energy.
Energy is converted from electrical energy to potential energy in a water-lifting electric pump. The pump's electric motor turns this electrical energy into mechanical energy, which is then used to physically
Question : Directions: In a certain code language TEARS is written as 20511819 and LUNGS is written as 122114719. How is DANCE written in that code language?
Option 1: 421326
Option 2: 526142422
Option 3: 51142422
Option 4: 411435
Correct Answer: 411435
Solution : Given: TEARS is written as 20511819 and LUNGS is written as 122114719.
The position value of each letter of TEARS –
Thus, TEARS is coded as 20511819. Likewise, the position value of
