Question

An article was sold for Rs 8400 thereby gaining 2/5 of the CP. Find the CP

Answer 1

Answer:

Selling price of each bullock = ₹ 8400. , gain(r) on one bullock = 20%.

C.P/S.P = 100/(100+r).

C.P./8400= 100/(100+20). Or. C.P. = 8400×(100/120)= ₹ 7000.

Let C.P. of other bullock =₹ x. There is neither loss nor gain , therefore:-

Total C.P. = total S.P.

₹ 7000 + ₹ x. = ₹8400 + ₹ 8400.

or, x = 16800–7000 = ₹ 9800. , thus , loss on other bullock=₹(9800-8400)=₹1400.

Loss % = 1400×100/9800 = 100/7 % or, 14.29 %. Answer.

Answer 2

Answer:

6000

Step-by-step explanation:

let cp be x

x+2/5*x=8400

5x/5+2/5x =8400

7/5x=8400

x=8400 * 5/7

=6000
