ATQ, Let the total number of boys in class ‘C’ = ‘10a’ Then, the total number of girls in class ‘C’ = 1.25 × 10a = ‘12.5a’ Let the total number of boys in class ‘D’ = ‘10b’ Then, the total number of girls in class ‘D’ = 1.40 × 10b = ‘14b’ According to the question, 10a + 12.5a = 360 Or, 22.5a = 360 Or, a = 360 / 22.5 = 16 And, 10b + 14b = 420 Or, 24b = 420 Or, b = 420 / 24 = 17.5 Required difference = 14b – 12.5a = 14 × 17.5 – 12.5 × 16 = 245 – 200 = 45
(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
