Question

solve the problems 4.......

Answer 1

Solution :

i ) Selling price of watch ( s.p ) = Rs1190

Loss ( L ) = 15%

Let the cost price = ( c. p )

c.p = ( 100 × s.p )/( 100 - L )

= ( 100 × 1190 )/( 100 - 15 )

= ( 100 × 1190 )/85

= Rs 1400

ii ) Cost price ( c.p ) = Rs 1400

gain ( g ) = 5%

Let the selling price = s.p

s.p = c .p × ( 100 + g )/100

= 1400 × ( 100 + 5 )/100

= 14 × 105

= Rs 1470
