Question
Selling price of article βAβ when sold at a profit
of 40% is Rs. 270 more than its selling price when sold at a loss of 40%. If the cost price of article βBβ is Rs. 72 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 40% = 1.40 Γ 100y = Rs. β140yβ 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, 140y β 60y = 270 Or, y = (270/80) Or, y = 3.375 So, cost price of article βAβ = 100 Γ 3.375 = Rs. 337.5 Therefore, cost price of article βBβ = 337.5 + 72 = Rs. 409.5
What will come in the place of question mark (?) in the given expression?
133 Γ· 19 X β576 + ? Γ· 2 = 32 X 7.525% of 250 + 32% of 200 = ? Γ· β 16
Find the value of βaβ in the following expression:
12 Γ a Γ 24 Γ· 8 + 72 β 46 = 170
447.8 × 441.2 ÷ 445 = 44 × 44?
- What will come in the place of question mark (?) in the given expression?
(β1089 + 47) X 4.5 = ? - β256 X 10 15% of 1800 + 22 = ?Β
13/3 β (23/6) = ? β (22/9)
(20% of 15% of 600 β 6) Γ 5 + 84 = ?2Β
