Let the cost price of the article be Rs.x. According to the question, => 550 – x = x – 420 => 2x = 970 => x = 485 Selling price of the product at profit of 20% = 485 x 1.2 = Rs.582
If + means ÷, - means x, x means +, ÷ means –, Find the value for 72 + 8 – 5 × 18 ÷ 5.
When a number is added to its multiple of 5 and its square, the sum of these three numbers is 91. Find the number.
If 84 × 13 = 8, 37 × 13 = 6, 26 × 11 = 6, then 56 × 22 = ?
What will come in place of question mark?
15× 24 × 32 = 585,
24 × 24 × 42 = 286,
39 × 14 × 27 = (?)
