Rice worth ₹96 per kg and ₹104 per kg are mixed with a third variety in the ratio 1 : 1 : 2. If the mixture is worth ₹113 per kg, the price of the third variety of rice per kg will be : |
₹109 ₹126 ₹117 ₹128 |
₹126 |
Cost of 1st variant = Rs. 96/kg Cost of 2nd variant = Rs. 104/ kg Cost of 3rd variant = Rs. X /Kg Ratio of their mixture = 1 : 1 : 2 Cost of mixture = Rs. 113, ⇒ (1 x 90) + (1 x 104) + (2 x X) = 4 x 113 ⇒ 90 + 104 + 2X = 452, ⇒ 200 + 2X = 452, ⇒ 2X = 252, ⇒ X = Rs. 126. Hence, the price of the third variety of rice per kg = Rs. 126. |
