Question
Selling price of article βAβ when sold at a profit
of 20% is Rs. 150 more than its selling price when sold at a loss of 30%. If the cost price of article βBβ is Rs. 80 more than that of βAβ, then find the cost price of article βBβ.Solution
Let the cost price of article βAβ = Rs. β100yβ Then, selling price of the article when it is sold at a profit of 20% = 1.20 Γ 100y = Rs. β120yβ And, selling price of the article when it is sold at a loss of 30% = 0.70 Γ 100y = Rs. β70yβ According to the question, 120y β 70y = 150 Or, y = (150/50) Or, y = 3 So, cost price of article βAβ = 100 Γ 3 = Rs. 300 Therefore, cost price of article βBβ = 300 + 80 = Rs. 380
β1936 + β3025 = ? % ofΒ 220
1231 + 1312 + 2113 β 3211 = ?
β324 * 6 β 20% of 180 + ? = 130% of 150
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
What will come in the place of question mark (?) in the given expression?
(87 + 79) X β9 - 298 = ? + β3600
12% of 10% of 15% of 5000 + (12 x 15) = ?
5490 ÷ 15 × 18 + 450 = ?
- What will come in place of (?) in the given expression.
(β of 450) β (β of 300) = ? 
β [? x 11 + (β 1296)] = 16
