Question : The average of three numbers of which the greatest is 16 is 12. If the smallest is half of the greatest, the remaining number is:
Option 1: 12
Option 2: 8
Option 3: 14
Option 4: 10
Correct Answer: 12
Solution : The greatest number = 16 The smallest number = half of the greatest number = $\frac{16}{2} = 8$ Let the third number be $z$. Average = $\frac{\text{Sum of all the observations}}{{\text{Total number of observations}}}$ $⇒\frac{16+8+z}{3}=12$ $⇒24+z=36$ $\therefore z =12$ Hence, the correct answer is 12.
Question : The average of the first three numbers is double the fourth number. If the average of all the four numbers is 12. Find the 4th number.
Option 1: $16$
Option 2: $\frac{48}{7}$
Option 3: $20$
Option 4: $\frac{18}{7}$
Correct Answer: $\frac{48}{7}$
Solution : Let the four numbers be $p, q, r$ and $s$. $⇒\frac{p+q+ r+s}{4}=12$ $⇒p+q+r+s=48$ ...(i) $⇒\frac{p+q+r}{3}=2s$ $⇒p+q+r=6s$ ...(ii) Putting equation (ii) in equation (i), we get, $⇒6s+s=48$ $⇒7s=48$ $\therefore s=\frac{48}{7}$ Hence, the correct answer is $\frac{48}{7}$.
Question : Directions: Three different positions of the same dice are shown. Find the number on the face opposite the face showing 2.
Option 1: 1
Option 2: 6
Option 3: 3
Option 4: 4
Correct Answer: 1
Solution : Taking dice positions 1 and 2 with 2 as common face,
Moving clockwise from the common face with 2,
Pairs of opposite faces –
So, the opposite face to the face containing 2 is 1. Hence, the first option is correct.
Question : In the given figure, the radius of a circle is $14\sqrt{2}$ cm. PQRS is a square. EFGH, ABCD, WXYZ, and LMNO are four identical squares. What is the total area (in cm2) of all the small squares?
Option 1: 31.36
Option 2: 125.44
Option 3: 62.72
Option 4: 156.8
Correct Answer: 125.44
Solution :
Given that the radius of the circle = $14\sqrt{2}$ cm The diameter of the circle = $2 \times 14\sqrt{2} = 28\sqrt{2}$ cm. The side of the larger square (PQRS) = $\frac{\operatorname{diameter}}{\sqrt2}=28$ cm. TO = half the side of the larger square = $14$ cm. The
Question : Dhiru can dig $\frac{1}{a}$ of a field in 20 hours. What fraction of the same field can Kaku dig 20 hours if the two of them can dig the field in 60 hours, working together at their respective rates?
Option 1: $\frac{(a-3)}{a}$
Option 2: $\frac{1}{3a}$
Option 3: $\frac{3a}{(3-a)}$
Option 4: $\frac{(a-3)}{3a}$
Correct Answer: $\frac{(a-3)}{3a}$
Solution : Time taken by Dhiru and Kaku together = 60 hours Efficiency of Dhiru and Kaku together = $\frac{1}{60}$ Time taken by Dhiru alone to dig $\frac{1}{a}$ of a field = 20 hours Efficiency of Dhiru = $\frac{1}{20a}$ Efficiency of Kaku = $\frac{1}{60}$ – $\frac{1}{20a}$ =
Question : In a bag, there are coins of 25 p, 10 p, and 5 p in the 2: 3: 5 ratio, respectively. If the coins' value is INR 5.25, how many 5 p coins are in the bag?
Option 1: 25
Option 2: 15
Option 3: 45
Option 4: 35
Correct Answer: 25
Solution : Let the number of 25 p coins, 10 p coins, and 5 p coins as 2$x$, 3$x$, and 5$x$ The total value of the coins is INR 5.25, which is equivalent to 525 paise. ⇒ 25(2$x$) + 10(3$x$) + 5(5$x$) = 525 ⇒ 50$x$ +
