Question
The marked price of an article is 30% higher than the
cost price. If a trader sells the articles allowing 10% discount to customer, then the gain percent will beSolution
let cost price (CP) = Rs 100 MP (marked price) = 30% more than cost price = 30/100 × 100 = 30 + 100 {here 100 = CP} MP =Rs 130 discount% = 10% discount = 10% of 130 = Rs 13 { ∵ discount = (discount percent / 100) × MP} So selling price SP = 130 – 13 = 117 { ∵ SP = MP – discount} gain = 117 – 100 = 17 { ∵ gain = SP – CP} gain % = (17/100) × 100 = 17%
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
? = 41.92% of 49.96% of (45.07 1.97 – 4.98 2.03 )
(15.15 ×  31.98) + 30.15% of 719.99 = ? + 124.34
15.2 x 1.5 + 258.88+ ? = 398.12 + 15.9
784.69 + 86.96 ÷ 29.01 = 40.01 + ? + 367.88
(29.892 × √290) + 32.98 × 6.91 = ?
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
 (3/5) of 3025 + (18² + 12²) = ? + 22.22% of 1125
24.75% of 20.125% of 30.05% of 2196.06 = ?Â
(799.81/64) ÷ (10/799.92) × (129.84/130) = ?
