Question

( Ans : 20 % loss) (but method I don't know...........so pls solve but answer should be 20 % only)

Answer 1

Answer:

12.25% gain I think

Step-by-step explanation:

15pencil cost =24 rupees

so cost of 5 pencils = 8 rupees(dividing 3 on both sides in the above equation)

she sells them 10 pencils at a cost of 18 rupees

so 10 pencils cost= 18 rupees( she sold)

cost of 5 pencils =9 rupees

so gain for selling 5 pencils = 1 rupees

so gain for selling 15 pencils = 3 rupees

%gain= (gain/cost price)×100= (3/24)×100=12.25%
