Question

Find the cost price when . Sp=rs 2431 and loss
% 6 whole 1 upon 2 %

Answer 1

SP=Rs 2431

L%=6.5%

Let CP=x

CP-L=SP

L=CP×L%/100

L=x×6.5/100

L=65x/1000

CP-L=SP

x-65x/1000=2431

1000x-65x=2431×1000

935x=2431000

x=2431000/935

x=2600

∴CP=Rs2600      Ans

Answer 2

formula to find CP = (100 / 100 - loss%) * SP

Therefore,

CP = (100 / 100 - 6.5) * 2431

CP = (100 / 93.5) * 2431

CP = (100 / 1) * 26

CP = 100 * 26

CP = Rs 2600
