(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
1299.999 ÷ 325.018 × 24.996 = ?
22% of 560 + 34% of 2160 × 5/12 =? + 16% of 920
If (x + 1/x) = 5, then value of x3 + 1/x3 is:
What value will come in place of (?) question mark in the given expression.
{ (18)² – (12)² } ÷ 6 = ?
Simplify:
(2√50 + 3√18 - √8) / √2
Simplify:

1672 ÷ 19 = ?% of 220
Calculate: 2.4 + 0.86 − 1.25 × 0.4
