- What will come in place of (?) in the given expression.
(18 × 2) + (72 ÷ 3) – 16 = ? What will come in place of (?) question mark in the following expression.
45% of 1600 + ?2 = 1044
(√2704 x 55)/(245 + 120) =?
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
- What will come in the place of question mark (?) in the given expression?
? = 20% of 25% of 15% of 12000 What will come in the place of question mark (?) in the given expression?
1020 ÷ 51 × 5 + 540 of 25% - 10 = ?2Â
- Simplify:

If √3n 729, then the value of n is equal to:
[∛(3375/19683  )- ∛(125/1728  )  ] ÷ ∛(64/729)  = ? - 3/8Â
6% of 520 + 5% of 620 = ?
