Question
In four years, the total age of 'Ravi' and 'Manoj' will be
60 years. Twelve years ago, Ravi was 10 years younger than Manoj. What will be Manoj's age 3 years from now?Solution
ATQ,
Let present ages be:
Ravi = p
Manoj = q
(p + 4) + (q + 4) = 60
⇒ p + q = 52 ——— (i)
p - 12 = q - 12 - 10
⇒ p = q - 10 ——— (ii)
(q - 10) + q = 52
2q = 62
q = 31
Manoj's age in 3 years = 31 + 3 = 34 years
?% of (168 ÷ 8 × 20) = 126
20% of 1500 – 75% of 200 = 125% of ?
Find the value of 16 X [(8 - 5) of 12 ÷ 4].
√196 + (0.25 × 144) + 19 = ? + 72
22 * 6 + 45% of 90 + 65% of 180 = ?
52% of 400 + √(?) = 60% of 600 - 25% of 400
(25 × 12 + 30 × 8 – 22 × 10) = ?
What will come in the place of question mark (?) in the given expression?
(240% of 175 ÷ √16) X 6 + 80% of 400 = ?3 + 179 + 42
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
808 ÷ (128)1/7 + 482 = 4 × ? + 846
