If the slant height of a cone is 60 cm and the radius of

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

25% of 1280 + (41 × 4) = ?² 

The sum of two numbers is 16 and their product is 63. The sum of their reciprocal is equal to:

10% of 100 + 14 = ?% of 120

18, 25, 33, 42, 52, 63, ?

24% of 35% of (5/8) of 2400 = ? 

Solve the following equation.

143 + 14.3 + 1.43 + 0.143 + 0.0143 =?

(1/8) × (256 × 2)/(8 × 4) + ?³ = 1730

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

(20% of 820 – 56 + 11 × 8) ^1/2 = ? – 6²

375% of 320 - 80% of 40 ÷ √256 = ?
