Question
A shopkeeper mixes two varieties of tea, one costing
₹300 per kg and the other ₹450 per kg, in the ratio 5:3. He sells the mixture at ₹400 per kg. Find his profit percentage.Solution
Let the quantity of the first variety (₹300/kg) be 5 kg and the second variety (₹450/kg) be 3 kg. Cost price of the mixture = (5 × 300 + 3 × 450) / 8 = (1500 + 1350) / 8 = ₹356.25 per kg. Selling price = ₹400 per kg. Profit percentage = [(400 − 356.25) / 356.25] × 100 ≈ 12.29%. Ans. b
(350/?) = 23 + 33
(630 ÷ 35) × 2 + 144 = ? × 2
?/4 ÷ 9/? = 15% of 800 + `1(2/3)` × `1(1/5)` × 1/2
236.23-653.23+696.23=?
72 × 2 = ? + 104 – 14
36895 - 4256 - 2233 = ?
What will come in the place of question mark (?) in the given expression?
3.6 X 15 + 4.5 X 12 = 40% of (? - 50)? = 15% of 2400 + 140% of 4200 – 12 3
√121 + √961− √289 =?2
