ATQ, We can say that the cost price of an apples be Rs. ‘100a’ So, selling price of an apples = 100a × 1.30 = Rs. ‘130a’ Marked price of an apples = (130a + 100a) × 1.30 = ‘299a’ So, discount allowed = 299a – 130a = Rs. ‘169a’ ATQ; 130a – 100a = 2400 Or, 30a = 2400 So, a = 80 So, discount allowed = 169 × 80 = Rs.13,520
3 √8 × √36 × 13 = ? × √169
If 0.17a = 11.9, find the value of a.
(320 + 342 + 530 + 915) ÷ (20 + 22 – x + 18) = 43, then the value of x is:
(15 × 225) ÷ (45 × 5) + 480 = ? + 25% of 1240
11 × 25 + 12 × 15 + 14 × 20 + 15 = ?
(175616)1/3 ÷ 8 × √2401/7 + √5184/8 – 18 = ?
520% of 360 – 12% of 400 = ? x 4
262 × 15 + (?)² = 4099
55 ÷ 11 × 6 + ?2 = 47 × 2
