If both pipes are open, then total units per hour empty the tank (A-B) = 5-8 = -3 units According to question, Tank has already filled 3/5 of its total capacity in the beginning = 3/5 × 80 = 48 units Time taken to empty the tank = 48/((-3)) = 16 hours
{18 × 5 + 48 ÷ 8} × 8 = ? + 684
Find the value of (x + y)² - (x - y)², where x = 15 and y = 7.
14 × 11 + 25 – ? = 21% of 300
654.056 + 28.9015 × 44.851 – 43.129 = ?
Simplify the expression -:
192.251 + 326.233 + 125.021 + 19.273 = ?
2/5){(3/5) × 750 + 40% of 375} = ? × 16
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
? = (25% of 20% of 800) × 8 – 25% of 260
2/5 of 3/4 of 7/9 of 7200 = ?
