Question

70. A shopkeeper purchases two varieties of rice, the price of the second kind being
50% more than that of the first. He mixes the rice and sells the mixture for Rs
27.84 per kg and earns a profit of 16%. If the ratio of the first to the second is 3
2 in the mixture, find the purchasing price of the costlier variety of rice.
​

Answer 1

Answer:

Step-by-step explanation:

Let 8 kg of first variety of rice and 5 kg of second variety is mixed.

Therefore, Cost price of 13 kg of rice

= Rs. (8×32+5×80)

= Rs.(256 + 400)

= Rs.656

S.P. of 13 kg of rice

= 72×13

= Rs.936

Gain = 936 - 656 = Rs.280

Gain per cent = 280656×100

= 43%
