Correct
Answer c
Explanation:
The average age = 25
∴ the total age = 25 × 3 = 75
Hence, the age of the eldest boy = 6/15 × 75 = 30

Question 17 of 20
17. Question
A bag contains 50p, 25p and 10p coins in the ratio of 5 : 3 : 2, amounting to Rs. 276. Find the number of coins of each type respectively.
Correct
Answer d
Explanation:
The ratio of the 50p, 25p,10p coins be 5x,3x,2x
(5x + 3x + 2x) = 276
(5x/2 + 3x/4 + 2x/10) = 276
(50x + 15x + 4x) /20 = 276
∴ x = 80
Hence the numbers of coins are,
50p = 5 × 80 = 400
25p = 3 × 80 = 240
10p = 2 × 80 = 160
Hence the answer is (400,240,160)
Incorrect
Answer d
Explanation:
The ratio of the 50p, 25p,10p coins be 5x,3x,2x
(5x + 3x + 2x) = 276
(5x/2 + 3x/4 + 2x/10) = 276
(50x + 15x + 4x) /20 = 276
∴ x = 80
Hence the numbers of coins are,
50p = 5 × 80 = 400
25p = 3 × 80 = 240
10p = 2 × 80 = 160
Hence the answer is (400,240,160)
Question 18 of 20
18. Question
If the radius and heights of the two cylinders are 4 : 7 and 3 : 8, then what is the ratio of its volume?
Correct
Answer b
Explanation:
Volume of the cylinder = (22/7)×r^2h
Ratio of two cylinders = (22/7)× (4)^2 × 3 :(22/7)× (7)^2 × 8
= 4 × 4 × 3 : 7 × 7 × 8 = 6 : 49
Incorrect
Answer b
Explanation:
Volume of the cylinder = (22/7)×r^2h
Ratio of two cylinders = (22/7)× (4)^2 × 3 :(22/7)× (7)^2 × 8
= 4 × 4 × 3 : 7 × 7 × 8 = 6 : 49
Question 19 of 20
19. Question
A, B and C divide an amount of Rs. 5000 amongst themselves in the ratio of 5:3:2 respectively. If an amount of Rs.600 is added to each of their shares, what will be the new ratio of their shares of the amount?
Correct
Answer a
Explanation:
A : B : C = 5 : 3 : 2
A = 5/10 × 5000 = 2500
B = 3/10 × 5000 = 1500
C = 2/10 × 5000 = 1000
If the amount Rs.600 is added to each of their shares then the new share becomes,
3100 : 2100 : 1600 = 31 : 21 : 16
Incorrect
Answer a
Explanation:
A : B : C = 5 : 3 : 2
A = 5/10 × 5000 = 2500
B = 3/10 × 5000 = 1500
C = 2/10 × 5000 = 1000
If the amount Rs.600 is added to each of their shares then the new share becomes,
3100 : 2100 : 1600 = 31 : 21 : 16
Question 20 of 20
20. Question
A shopkeeper sold an article for Rs. 1,380 at a loss of 8%. At what price should it be sold to gain a profit of 8%?
Correct
Answer b
Explanation:
Let the cost price of article = Rs. x
According to question,
x * 92/100 =1380
x = Rs.1,500/-
Required price = 1500 * 108/100
= Rs.1620
(or)
Shortcut method:
S.P_{1} / (100-loss%) = S.P_{2 }/(100+Profit%)
1380/92 = S.P_{2} / 108
S.P_{2} = 1620
Incorrect
Answer b
Explanation:
Let the cost price of article = Rs. x
According to question,
x * 92/100 =1380
x = Rs.1,500/-
Required price = 1500 * 108/100
= Rs.1620
(or)
Shortcut method:
S.P_{1} / (100-loss%) = S.P_{2 }/(100+Profit%)
1380/92 = S.P_{2} / 108
S.P_{2} = 1620
