Let the initial number of crabs in the pond be ‘x’ Therefore, initial number of fish in the pond = (x – 60) According to the question, 0.8x/(x – 60 + 80) = 3/4 Or, 3.2x – 3x = 60 Or, x = 60/0.2 = 300 Therefore, initial number of fish and crabs in the pond = (x + x – 60) = 540
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
(180 ÷ 22 ) ÷ (60% of 30) = (? ÷ 2)
136% of 560 - 2/7 of 630 + 45% of 420 =?
Determine the simplified value of the given mathematical expression.
1500 × 60% of 25% = ? 2
53 – 8 = ? + 126
Find the Value of
? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
