8
7
10
15
20
Solution:
Let there are n no. of males
∴ (n + 15) × 18 = 240 + 20n
⇒ n = 15
∴ (n + 15) × 18 = 240 + 20n
⇒ n = 15
Q2. The difference between the present age of Arun and Deepak is 14 years. Seven years ago the ratio of their ages was 5 : 7 respectively. What is Deepak’s present age ?
49 years
56 years
63 years
35 years
30 years
Solution:
Let Deepak’s present age = (7x + 7) years
Arun’s present age = (5x + 7) years
ATQ,
7x – 5x = 14
x = 7
∴ Deepak’s present age = 49 + 7 = 56 years
Arun’s present age = (5x + 7) years
ATQ,
7x – 5x = 14
x = 7
∴ Deepak’s present age = 49 + 7 = 56 years
