Question

If cost of 50kg rice is Rs.1400.Find the cost of 75kg rice?

Answer 1

Let the mass equal to x of rice
$50x = 1400 \\ x = \frac{1400}{50} \\ x = 28 \\ 75x = 28 \times 75 \\ 75x = 2100$

Answer 2

HEY BUDDY .
YOUR SOLUTION IS HERE.

Cost of 50kg rice = Rs.1400
Cost of 1kg rice = Rs. 1400/50
= Rs. 28
Cost of 75 kg rice = Rs. 75 ×28
= Rs. 2100
