Question
A merchant marked the price of an article by increasing
its production cost by 40%. Now he allows 20% discount and gets a profit of Rs. 48 after selling it. The production cost isSolution
let the production cost(PC) be Rs 100 marked price (MP) = 140% production cost {production cost = Rs 100} MP = Rs 140 discount = 20% discount = 20/100 × 140 { ∵ discount = (discount percent / 100) × MP} discount = Rs 28 selling price (SP) = Rs 112 profit = SP - PC = 112 -100 = 12 here Rs 12 is when PC = Rs 100 now when profit = Rs 48 { ∵ 12 × 4 = 48} PC = 4 × 100 = Rs 400
What value should come in place of (?) in the given expression.
{(36)² − (28)²} ÷ 8 + 9² = ?
Simplify: 48 ÷ 4 × 2 + 5 × (7 − 3)
?% of 18% of 2600 = 234
What will come in the place of question mark (?) in the given expression?
(12.09)2 × 5.98 ÷ 26.95 = ? + 25
What will come in the place of question mark (?) in the given expression?
(555 + 385 - 535) ÷ 15 X ? = 36 X 30
(11/12) × (18/22) × (4/3) + 3 = ?2
The value of (43-3× (4×6+12/6 ×6-4×5) +4)?
(392 + 427 + 226 – 325) ÷ (441 + 128 – 425) = ?
The value of [(3√2+2) × (3√2-2)] of 13 + 15 is:
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
