Question
A shopkeeper bought 30 articles at Rs. 12 each. He sold
10 at 40% profit, 15 at 10% loss, and the rest at 5% loss. Determine the overall profit or loss.Solution
ATQ, Total cost price of all the articles = 30 Γ 12 = Rs. 360. Total selling price of all the articles = {10 Γ (12 Γ 1.4) + 15 Γ (12 Γ 0.9) + 5 Γ (12 Γ 0.95)} = 168 + 162 + 57 = Rs. 387 Overall profit = 387 - 360 = Rs.27
What will come in the place of question mark (?) in the given expression?
(3.2 Γ 35 + ?) Γ· β16 = 38.5

15% of 360 Γ 20% of ? = 324
240 + 25% of 420 β 145 =? + (2.5 + 8.5) 2
Find the value of x.
Β β441 Γ· 21+ β400 = 1 Γ x
48% of ? = 10176
? = 6.25% of 240 + 252 + 172 β 16 Γ 17
√10404 + √9604 - β1728 - β42875 = ?
72 Γ 2 = ? + 104 β 14
(64 Γ 16) Γ· (4 Γ 16) 3 Γ 256 2 = 4 ?
