Question
An article is sold for Rs. 480 at 20% loss. If this
article was sold at 12.5% profit, what would have been its selling price?Solution
Given, SP = Rs. 480, Loss% = 20% Then, => CP = SP/(1 – (loss%100)) => CP = 480/(1 – 20/100) = 480/0.8 => CP = Rs. 600 Hence, The required selling price = CP × (1 + (profit%/100)) = 600 × (1 + 12.5/100) = Rs.675
`(21 xx 51 + 54)/(9 xx 14 - 30 )` =?
Simplify: 72 ÷ 6 × 3 − 8 + 4
808 ÷ (128)1/7 + 482 = 4 × ? + 846
120% of 25 + 80 X 2 = ?2 - 6
1540 ÷ 7 - 184 ÷ 8 = ?
What will come in place of (?) in the given expression.
(18 + 24 ÷ 6) × 2 - 5 = ??/343 = 7/?
- Simplify:

What will come in the place of question mark (?) in the given expression?
34 X 11 - ? + 36 = 3 X 75 + 125
(168 ÷ 12 + 19 × 64)/(22+1) = ?
