Amit is five years older than Vaibhav at present. After four years the ratio of their ages will be 5 ∶ 4. What is Amit's age (in years) at present?

Detailed Solution for RRB NTPC Mock Test - 9 (English) - Question 4

Let Vaibhav’s age = a and Amit’s age = 5 + a

(Amit's age after 4 years)/(Vaibhav's age after 4 years) = 5/4

⇒ (5 + a + 4)/(a + 4) = 5/4

⇒ 20 + 4a + 16 = 5a + 20

⇒ 5a – 4a = 16

⇒ a = 16

∴ Amit’s age = 5 + a = 5 + 16 = 21

RRB NTPC Mock Test - 9 (English) - Question 5

A man spends 80% of his income and saves the rest. If his income and spending both increases by 10%, then what is the percentage change in his savings?

Detailed Solution for RRB NTPC Mock Test - 9 (English) - Question 5

Let,

Income of the man in Rs. = x

He spends 80%

∴ Amount of spend in Rs. = 0.80x

∴ Amount of savings in Rs. = x - 0.80x = 0.20x

If his income and spending both increases by 10%,

New amount of Income Rs. = 1.10x

New amount of spend in Rs. = (1.10) × (0.80x) = 0.88x

∴ New amount of savings in Rs. = 1.10x - 0.88x = 0.22x

∴ Percentage increase in savings= [(0.22x - 0.20x)/0.20x] × 100% = (0.02/0.20) × 100% = 10%

∴ 10% increase in savings.
