Selling price of the article = a + (4a/5) = Rs. (9a/5) So, (9a/5) = (2.5 × a – 300) × 0.75 Or, 1.8a = (2.5a – 300) × 0.75 Or, 2.4a = 2.5a – 300 Or, 0.10a = 300 Or, a = 3000 So, marked price of the article = 2.5 × 3000 = Rs. 7500
1000÷ 250 = ( 3√? × √1444) ÷ ( 3√512 × √361)
1540 ÷ 7 - 184 ÷ 8 = ?
12.232 + 29.98% of 539.99 = ? × 5.99
√256 * 3 – 15% of 300 + ? = 150% of 160
18 × 15 + 86 – 58 =? + 38
[5 X {(52 X 5) - 10} + 50 of 20] = ?
4(1/3) × 2(11/14) = 50% of ? + 86/11
(15 x 6 + 60% of 500 - 16 x 7) = ?
25% of 140 + 2 × 8 = ? + 9 × 5
If a nine-digit number 389x6378y is divisible by 72, then the value of √(6x + 7y) will be∶
