Answer Key with Explanation:
Direction (01-05):
1. Expense on Rent in May
= 19630 × 22 / 100 = 4318.6
Expense on Clothes in April
= 17250 × 20 / 100 = 3450
Required % = (4318.6 – 3450) / 3450 × 100
= 25.17%
≈ 25%
Answer is: d)
2. Expense on Food in April = 17250 × 40 / 100 = 6900
Expense on Food in May = 19630 × 42 / 100 = 8244.6
Required % = (8244.6 – 6900) / 6900 × 100
= 19.48%
Answer is: c)
3. Total expenses on Entertainment and clothes together in both the months
In April = 17250 × 9/100 + 17250 × 20/100
= 1552.5 + 3450
= 5002.5
In May = 19630 × 6 / 100 + 19630 × 22/100
= 1177.8 + 4318.6
= 5496.4
Total = 5002.5 + 5496.4 = 10498.9 ≈ 10500
Answer is: b)
4. Expense on clothes in May = 19630 × 22 / 100 = 4318.6
Expense on School fees in April = 17250 × 11 / 100 = 1897.5
Required %
= (4318.6 – 1897.5) / 1897.5 × 100
= 2421.1/1897.5 × 100
= 127.59%
Answer is: c)
5. Average expense on entertainment and school fees in May = (19630 × 6 / 100 + 19630 × 8 / 100) / 2
= (1177.8 + 1570.4) / 2
= 2748.2 / 2 = 1374.1
Average expense on food and clothes in April = (17250 × 40 / 100 + 17250 × 20 / 100) / 2
= (6900 + 3450) / 2
= 10350 / 2
= 5175
Required difference = 5175 – 1374.1 = 3800.9 ≈ 3800
