Let the no of computers of brand Y = n and the cost of 1 computer of brand Y = Re. k Original cost of brand Y computer = Rs. kn and original cost of brand X computer = Rs. 3 x 3k = 9k Total original cost = Rs.(kn + 9k) In the case of executed order, Cost of brand X computer = Rs. 3kn And cost of brand Ycomputer = Rs. 3k Total cost of executive order = Rs. (3kn + 3k) As per the question, 150% of (kn+ 9k) = 3kn + 3k 150% of (n+ 9) = 3n + 3 ⇒ 150/100 x (n + 9) = 3n + 3 ⇒ 3/2 x (n + 9) = 3n + 3 ⇒ 1/2 x (n + 9) = n + 1 ⇒ n + 9 = 2n +2 ⇒ n = 7 Required ratio = 3 : 7
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
Find the simplified value of the given expression.
{12.75 × √64 + 13.5 × √(√256)} ÷ 6 + 49.5 ÷ 5.5
(√7225 x √1225)/(√625) = ?
The value of {5 − 5 ÷ (10 − 12) × 8 + 9} × 3 + 5 + 5 × 5 ÷ 5 of 5 is:
(8.6 × 8.6 + 4.8 × 4.8 + 17.2 × 4.8) ÷ (8.62 – 4.82 ) = ? ÷ 19
