Question
A shopkeeper bought 60 kg of apples at ₹80 per kg and
40 kg of oranges at ₹60 per kg. If he wants to make a profit of 20% on the total cost, at what price per kg should he sell the mixed fruits?Solution
Solution: Total cost of apples = 60 * 80 = ₹4,800. Total cost of oranges = 40 * 60 = ₹2,400. Total cost = 4,800 + 2,400 = ₹7,200. Desired profit = 20% of 7,200 = 1,440. Total selling price = 7,200 + 1,440 = ₹8,640. Total weight = 60 + 40 = 100 kg. Selling price per kg = 8,640 / 100 = ₹86.40. Correct answer: E) ₹86.40
33 + ? = 40% of 1420
What will come in the place of question mark (?) in the given expression?
? = 60% of 48% of (20 × 350) + 180
- What will come in place of (?) in the given expression.
(84 + 36 ÷ 6) × 2 = ? - What will come in the place of question mark (?) in the given expression?
(120 - ?) ÷ 2 + 35 = 86 - 11 1365 ÷ 15 + (? ÷ 5) = 62 × 3.5
Evaluate
64 ÷ 4 of 5 of [10 ÷ 5 of (9 ÷ 3 + 2)] + (9 ÷ 3 + 1)
150% of 850 ÷ 25 – 25 = ?% of (39312 ÷ 1512)
15.8% of 9000 + 20.4% of 7500 = 30% of ?
Simplify the expression:
(4x² - 16) / (2x - 4)
(1/2) – (3/5) + 3(1/3) = ? + (5/6)
