Let the cost price of article ‘A’ = Rs. ‘100y’ Then, selling price of the article when it is sold at a profit of 35% = 1.35 × 100y = Rs. ‘135y’ And, selling price of the article when it is sold at a loss of 40% = 0.60 × 100y = Rs. ‘60y’ According to the question, 135y – 60y = 120 Or, y = (120/75) Or, y = 1.6 So, cost price of article ‘A’ = 100 × 1.6 = Rs. 160 Therefore, cost price of article ‘B’ = 160 + 80 = Rs. 240
(12% of 1250 + 85% of 400) x 10 = ?2
What will come in the place of question mark (?) in the given expression?
(70 × 8 ÷ 10) × 5 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
The value of (40 + 3/4 of 32) /[37 + 3/4 of (34-6)] is:
236.23 - 653.23 + 696.23 = ?
7.4 × 8.2 + 3.5 × 4.5 = ? + 11.5 × 2.5
800 + 900 X (3)-2 - ? = 25 X 60 ÷ 2
808 ÷ (128)1/7 + 482 = 4 × ? + 846
30% of 215 + 135% of ? = 469.5
