The simple interest on a sum of Rs X in 5 years is

What will come in the place of question mark (?) in the given expression?

(87 + 79) X √9 - 298 = ? + √3600

What will come in the place of question mark (?) in the given expression?

? = 60% of 48% of (20 × 350) + 180

? = 60% of 2500 + 85% of 2000 – 5³

14% of 700 + 15% of 900 + 10% of 160 = ?

30% of 8/5 × 5/7 × 2870 =?

(3500 ÷ √1225) × √(20.25) = ? ÷ 4

36 × 15 + 20% 1250 = ? + 296

Simplify the following expression:

    (525 +175) ² - (525 – 175) ² / (525 × 175)
