Question
My sister is 5 years elder to me. My father was 30
years of age when my brother was born while my mother was 28 years of age when I was born. If my brother was 6 years of age when my sister was born, then what was the age of my father and mother respectively when my sister was born?Solution
Clearly, my sister was born 5 years before I was born and 6 years after my brother was born. So, father’s age when sister was born = (30 + 6) years = 36 years Mother’s age when sister was born = (28 – 5) years = 23 yearsÂ
15.99% of 549.99 ÷ 11.17 = ? ÷ 20.15
74.91% of 639.95 – 599.98% of 45 + 119.987 = ?
(4.88 × 5.76)2 - ?2 = 39.89 × 19.86

(1800.23 ÷ 29.98) + (816.32 ÷ 23.9) + 1634.11 = ?
1449.98 ÷ 50.48 × 10.12 = ? × 2.16
36.05 × 5.02 + 12.052 = ? + 9.09 × 4.04Â
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
