Which of the following is the scientific name for the

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

(16 × 22 + 23) ÷ 15 + 24 = ?² – 16 × 2

? ÷ 62 × 12 = 264

420 ÷ 7 + 140 % of 20 + ? × 13 = 18 × 15

779 + 136 – 334 = 270 + 121 + ?

(72 + 30) ÷ 6 + [{75 ÷ 25) + 6} × 2] = ?

(18 ² – 17 ²) x (1/5) + ? = 148

Simplify:

0.48 ÷ 0.06 + 0.75 × (4/5)

(7/4×18/21)+ (51/7× 28/17) + (25/2  × 48/10) =?

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

(5/8) × 1600 + (2400 ÷ 25) = ?
