First part = x and second part = 84 – x => (x/4)/[(84-x)/5] = 1/2 ⇒ x/4 × 5/(84-x) = 1/2 ⇒ 10x = 336 - 4x ⇒ 14x = 336 ⇒ x = 24 Second part will be 84 – 24 = 60 Required percentage =(24/60) × 100 = 40%
24% of 150% of 500 + 140 = ? × 8
(25)² × 4 ÷ 5 + (3)³ + 48=? + 425
322 – 182 + 11 × 24 = ?
15% of 5000 - √900 = ? + 10% of 1800
360 ÷ 4 ÷ 3 = 150 – ?
[(4√ (7) +√ (7))× (7√ (7) + 6√ (7))] - 87 = ?
...25639 – 5252 – 3232 = ?
∛157464 =?
702 ÷ 26 + 142 - 20% of 310 = ? - 15% of 420
