Question

The cost of a fan and a watch is ₹3600. If the cost of watch is 7 times the cost of fan,
find the cost of the fan.

Answer 1

Answer:

Cost of fan = x = 450 rupees

Step-by-step explanation:

Let the cost of the fan be x

The cost of the watch is 7 times or 7x

Total cost = cost of fan + cost of watch = x+7x = 8x

Also, total cost = 3600 rupees

So, we can say 8x = 3600 rupees

x = 3600rupees, / 8

x = 450 rupees

So cost of fan = x = 450 rupees

If you also need cost of watch then,

Cost of watch = 7x = 450×7 = 3150 rupees

Answer 2

Answer:

The cost of fan is ₹450.

Step-by-step explanation:

Let the cost of fan be x

Cost of watch = 7x

Total cost = Cost of fan + Cost of watch

3600 = x + 7x

3600 = 8x

3600÷8 = x

450 = x

Therefore, Cost of fan = x = ₹450

And, Cost of watch = 7x

=7 × 450

= ₹3150
