The average age of (husband, wife, child) before 4 year=24 Total age of (husband, wife , child) before 4 year=24×3=72 Total age of (husband, wife, child) present =72+12=84 years. The average age of husband and child before 5 years=19 years Total age of husband and child before in present = (19×2)+10=48 years so now present age of wife = is 84-48=36 years
96% of 4500 – 34% of 650 = ?
√10000 × √8100 - (50)² = √(?) + (80)²
44% of 1250 + 46 × 34 = 40% of ? + 1154
What will come in the place of question mark (?) in the given expression?
(18 × 8 ÷ 12) × 10 = ?
Solve: 3/4÷2/3
(√529 + 63 /8)% of 800 = ?% of 250
(190/38) × (55/5) + (306/18) = ?
