Tea worth ₹ 126 kg and ₹ 135 per kg are mixed with a third variety in the ratio 1 : 1 : 2 . If the mixture is worth ₹ 153 per kg, the price of the third variety per kg will be?
Correct Answer: ₹ 175.5
Explanation:
Let the cost of third variety tea will be ₹ N per kg
According to the question,
(126 + 135 + 2N)/4 = 153
⇒ (261 + 2N) = 4 x 153
⇒ 2N = 612 - 261 = 351
∴ N = 351/2 = 175.50
⇒ N = ₹ 175.5
Hence, the cost of third variety tea is ₹ 175.50 per kg .
