Question
Who invented the light bulb?
Solution
Thomas Edison is credited with inventing the first practical incandescent light bulb in 1879.
? ÷ [35% of 379 - 34(4/5)] = 0.4
2 X 25 + (30% of 80) ÷ (10% of 120) = ?
- What will come in the place of question mark (?) in the given expression?
[{(224 + 14 × 23) – 187} × (672 ÷ 28 – ?)] = 1795 1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)     Â
- What will come in place of (?) in the given expression.
(2/3 of 96) ÷ (4/5 of 25) = ? (288 ÷ 12 + 15 × 5 + 124) = ?
 √256 * 4 – 30% of 190 + ? = 110% of 220
Simplify the following expressions and choose the correct option.
(56% of 750) − (3/8 of 320) + (2.5)² = ?
What will come in the place of question mark (?) in the given expression?
(252 + 198) ÷ ? + 126 ÷ 3 = 144 ÷ 2
Simplify: 72 − 18 ÷ 3 × 2 + 5 × 3
