Question

What will be the cost of 4 cans of juice, if the cost of 6 cans of juice is 210?
​

Answer 1

Answer:

140

Step-by-step explanation:

Cost of 6 cans of juice = 210

Cost of 1 can of juice = 210/6 = 35

cost of 4 cans of juice = 35 × 4 = 140

Answer 2

Solution!!

The concept of unitary method has to be used here. We have to find the cost of 1 can and then the cost of 20 such cans of juice.

→ Cost of 6 cans = Rs 210

Now, we have to find the cost of 1 can. So, we will divide.

→ Cost of 1 can = Rs 210 ÷ 6

→ Cost of 1 can = Rs 35

We know the cost of 1 can of juice so we can easily find out the value of 4 such cans by multiplication.

→ Cost of 4 cans of juice = Rs 35 × 4

→ Cost of 4 cans of juice = Rs 140

The cost of 4 balls is Rs 140.
