1.	The cost of 12 quintals of soyabean is Rs 36,000. How much will 8 quintals cost?
Answer» Let the cost of 8 quintals of soyabean be Rs x. The quantity of soyabeans and their cost are in direct proportion. \(\therefore \frac{12}{36000} = \frac{8}{x}\) ∴ 12x = 8 × 36000 ….(Multiplying both sides by 36000x) \(\therefore x = \frac{8 \times 36000}{12} = 24000\) ∴ The cost of 8 quintals of soyabean is Rs 24000.

Let the cost of 8 quintals of soyabean be Rs x. The quantity of soyabeans and their cost are in direct proportion.

\(\therefore \frac{12}{36000} = \frac{8}{x}\)

∴ 12x = 8 × 36000 ….(Multiplying both sides by 36000x)

\(\therefore x = \frac{8 \times 36000}{12} = 24000\)

∴ The cost of 8 quintals of soyabean is Rs 24000.
