Question
A is 5 years older than B. After 3 years, ratio of the
age of B and that of her father will be 1:3. Present age of B’s father is 45 years and C is 4 years older than A. Find the respective ratio of the present ages of B and C. TYPE TSolution
After 3 years, Age of B’s father = 45 + 3 = 48 years Age of B = 1/3 × 48 = 16 years Present ages, B = 16 – 3 = 13 years A = 13 + 5 = 18 years C = 18 + 4 = 22 years Required ratio = 13:22
41.66% of 888 + 66.66% of 1176 = ?2 - 4√ 16 Â
Evaluate: 320 − {18 + 4 × (21 − 9)}
Simplify: 72 ÷ 6 × 3 − 8 + 4
118 × 6 + 13 + 83 = ?
Simplify the following expression:
  (400 +175) ² - (400 – 175) ² / (400 × 175)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
(75 + 0.25 × 10) × 4 = ?2 - 14
26% of 650 + 15% of 660 – 26% of 450 = ?
115% of 40 + 3 × 4 = ? × 11 – 8
