Find the simplified of the following expression:

Simplify the following expression:

416 ÷ 8 + 13² – 25% of 420 = ?

9 × 4 ^? ÷ 16 = 144

42 + 52% of 300 - ?% of 200 = 88

What value should come in place of (?) question mark in the given expression.

17 × 15 − 96 ÷ 8 + 6² = ?

19 × ? = 361 ÷ 19

Simplify the following expressions and choose the correct option.

(3/7) of {350 − [42 ÷ (3/2)]} = ?

15% of ? = 30% of 320 + 17 ×√676 – 63.5 × 8

390/? = √256 + 3.5
