If two qualities of pulses 'X' and 'Y' of prices ₹100 and ₹150 per kg are mixed in the ratio 7 : 20, then what is the price (in ₹) of this mixture of pulses (correct to the nearest Rupees)?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 137.
Given:
X qualities of pulses cost = Rs. 100/kg
Y qualities of pulses cost = Rs. 150/kg
The ratio of pulses X and Y is 7:20
Explanation:
According to the question
The price of the mixture of pulses = (100 × 7 + 150 × 20)/(20 + 7)
⇒ (700 + 3000)/27
⇒ 3700/27
⇒ Rs. 137
