Question
Avni’s present age is 4 times of Pooja’s
age. The sum of the present ages of Avni, Pooja and Avni’s brother is 178 yrs. Avni’s brother’s present age is 11/9 that of Avni. What is the difference between Pooja’s present and Avni’s brother’s present age?Solution
Let Avni’s age be x yrs. x + 11/9 x + x/4 = 178 89/36 x = 178 x = 72 yrs. Pooja’s present age = 72/4 = 18 yrs Avni’s brother’s present age = 72 × 11/9 = 88 yrs ∴ Required difference = 88 – 18 = 70 yrs.
(22 × 52 ) + 4 × 6 = ? - √324
What should come in place of (?) question mark in the given expression.
 (25% of 320) + (3/8 of 400) − 30 = ?
(5832)1/3  × 10.11 × 11.97 ÷ 16.32 = ? + 45.022
82% of 400 + √(?) = 130% of 600 - 85% of 400
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
Simplify: (1 ÷ 0.08)
What should come in place of (?) question mark in the given expression.
{ (144 ÷ 12) × 5 } − (18 ÷ 3) = ?
Simplify the following expressions and choose the correct option.
(3/4 of 256) + (2/5 of 150) - (72 ÷ 7)
464 + 181 +? = (154 × 25) - (15) 2 Â
15% of 1800 + 22 = ?Â
