In what ratio must a grocer mix two varieties of pulses costing Rs. 72 and Rs. 96 per kg, respectively, so as to get a mixture worth Rs. 83 per kg?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 13 : 11.
Let the ratio be x kg of A and y kg of B
72x + 96y = 83(x + y)
⇒ 72x + 96y = 83x + 83y
⇒ 13y = 11x
⇒ x/y = 13/11
