Answer 1

3 kg spinach costs Rs 15

So, 1 kg spinach will cost Rs 5 (15/3)

Therefore, 8 kg spinach will cost Rs 40 (5x8)

Similarly,

5 kg tomato cost Rs 20

So, 1 kg tomato costs Rs 4 (20/5)

Therefore, 8 kg of tomato will cost Rs 32 (4x8)

Answer 2

Answer:

Cost of 8 kg spinach and 8 kg tomato = Rs.72  

Given data

cost of 3 kg spinach = Rs. 15

cost of 5 kg tomato = Rs.20

here we need to find cost of 8 kg spinach and 8 kg tomato

Step-by-step explanation:

from given data cost of 3 kg spinach = Rs. 15

                   then cost of 1 kg spinach = 15/3 = Rs.5  

cost of 8 kg spinach  = 8×5 = 40 Rs.

                cost of 5 kg tomato = Rs.20

        then cost of 1 kg tomato = 20/5 = Rs.4

cost of 8 kg tomato  = 8×4 = Rs. 32

Total cost for 8 kg spinach and 8 kg tomato = Rs.40+Rs.32 = Rs.72
