a retailer buys some dry fruits at rs 50rs,40rs,30rs per kg he mixes them in the ratio 3:4:5by weight and sells at profits of 30% find the SP Of dry fruit per kg

Answer 1

The sp of dry fruit per kg = Rs. 49.83

Step-by-step explanation:

Let the retailer buy 3x ,4x and 5x kg dry fruits.

Total cost price of dry fruits = Rs.(3x×50 + 4x×40 + 5x×30) = Rs (150x +160x+150x) = Rs.460x

Given , he sells dry fruits at profit 30%.

So total selling price = Rs. 460x × $\frac{130}{100}$ = Rs. 46×13x

Total weight of dry fruits =( 3x + 4x +5x) kg = 12x kg

The sp of dry fruit per kg = Rs. $\frac{598x}{12x}$ = Rs.49.83
