Question
Selling price of article βAβ when sold at a profit
of 50% is Rs. 180 more than its selling price when sold at a loss of 40%. 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 50% = 1.50 Γ 100y = Rs. β150yβ And, selling price of the article when it is sold at a loss of 40% = 0.60 Γ 100y = Rs. β60yβ According to the question, 150y β 60y = 180 Or, y = (180/90) Or, y = 2 So, cost price of article βAβ = 100 Γ 2 = Rs. 200 Therefore, cost price of article βBβ = 200 + 80 = Rs. 280
?2 - 12.5% of 647.99 = 24.98% Γ 363.97 + 5% of 1059.98Β
?% of (150.31 Γ· 14.97 Γ 50.011) = 319.98
What approximate value will replace the question mark (?) in the following?

- 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.)
386.99 + 397.99 + ? - 232.02 = 35.02 Γ 31.99
2660.03 Γ· 94.98 x 59.9 = ? + 20.32

(80.95) (1/4) + (3.05) 3 - 119.78 Γ 2.15 + (14.98)2 = ?
