Question
A shopkeeper bought 3 different types of goods: 100
items at ₹50 each, 200 items at ₹40 each, and 50 items at ₹60 each. If he sold all items at ₹55 each, what is his percentage profit or loss?Solution
Cost price (CP) = (100 × 50) + (200 × 40) + (50 × 60) = 5000 + 8000 + 3000 = ₹16,000 Selling price (SP) = Total items × ₹55 = (100 + 200 + 50) × 55 = 350 × 55 = ₹19,250 Profit = SP - CP = 19,250 - 16,000 = ₹3,250 Profit percentage = (Profit / CP) × 100 = (3250 / 16,000) × 100 = 20.31% Correct answer: d) 20.3% profit
(64/25)? × (125/512)?-1 = 5/8
If (3 × 144 – 252 ÷ 14) ÷ 18 = √1024 – x, then find the value of ‘x’.
- What will come in the place of question mark (?) in the given expression?
32% of 74% of ? = 16% of 37% of 180 5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
1120 / √x = 80 Then x = ?
√? + √1296 + √729 = 464/4
What will come in the place of question mark (?) in the given expression?
28 × 15 + 48% of ? = 780
(-251 × 21 × -12) ÷ ? = 158.13
17% of 250 + ? = 108
