Time taken by 2 men to complete the work = (3 × 4)/2 = 6 days Time taken by 6 women to complete the work = (4 × 9)/6 = 6 days Therefore, required time = (6 × 6)/(6 + 6) = 36/12 = 3 days
√64 of √225 = √(25 + ?) X 12
808 ÷ (128)1/7 + 482 = 4 × ? + 846
(5/7) of (7/11) of (3/5) of 52% of 4400 = ? - (44)2 + (50)2 - (62% of 1750) - (188 ÷ 9.4)
56 × 18 + ? × 21 – 49 × 12 = 63 × 26
Simplify the expression:
(4x² - 16) / (2x - 4)
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
245 + (45 ÷ 3 + 5) × 6 - 125 = ?
√49 + √144% of 3600 = ?
