Question

jayanth paid rs 240 for 1 jacket and 6 helmets. the cost o of jacket is as twice of the cost of helmet. find the cost of 5 such jackets

Answer 1

Let the cost of helmet be x.

Cost of jacket is twice.

So cost of jacket=2x.

Now 2x+6x=240

8x=240

=x=240/8

=x=30

Cost of 5 jackets

=5*2x

=10x

=10*30

=300

Thus your answer is 300.

Hope it helps you.

Have a nice day:-)

Answer 2

Let the cost of jacket be 2x and helmet be x.
(A.T.Q)
2x + 6x = 240
8x = 240
x = 240/8
x = 30
Hence, cost of jacket = Rs60 and cost of helmet = Rs30.

cost of 5 jackets = 5 × Rs60 = Rs300
