20% profit, then how many apples will be sold for Rs.78?Solution
Cost price of 1 apple = 50/20 = Rs.2.50 Selling price of 1 apple = 2.50 × 120% = Rs.3 Required number = 78/3 = 26
Simplify the expression:
(5x + 15) / (x² + 3x)
Simplify: 6(x³ − 2x² + 3x) − (x³ + 2x − 3).
- Find the value of the expression:
15 + 10 – 6 × [20 + 8 – 2 × (50 – 35)] (5/8 + 7/12) x 168 = ? + 93 - 25
What will come in the place of question mark (?) in the given expression?
(√441 + √729) X 8 = ? + 518 ÷ 2
1.25 × 36 + 2.75 × 40 = ? × 3.1
What is (0.08% of 0.008% of 8)1/9 ?
- What will come in the place of question mark (?) in the given expression?
62.5% of 120 + ? = (720 + 90) ÷ √36 What will come in place of (?) in the given expression.
40% of (120 + 80) + 25% of 160 = ?4567.89 - 567.89 - 678.89 = ?
