Question

A person buys electronic goods worth ₹ 10,000 for which the sales tax is 4% and other material worth ₹ 15,000 for which the sales tax is 6%. He manufactures a gadget using all these and sells it at 15% profit.What is his selling price?

Answer 1

Solution :

i ) Cost price of electronic

goods( c.p) = Rs 10000

sales tax ( t ) = 4%

Bill amount (b1) = c.p[(100+t)/100]

= 10000[(100+4)/100]

= 100 × 104

= Rs 10400 ----( 1 )

ii ) cost price of other

materials (c.p) = Rs 15000

sales tax (t) = 6%

Bill amount (b2) = 15000[(100+6)/100]

= 150× 106

=Rs 15900 ------( 2 )

iiii ) If he manufacturers a gadget

using all the above items then

Total cost price of the gadget (c.p)

= b1 + b2

= Rs 10400 + Rs 15900

= Rs 26300

Gain ( g ) = 15%

Let Selling price of the gadget=

( s.p ) = c.p[ ( 100 + g )/100 ]

= 26300 [ ( 100 + 15 )/100 ]

= 263 × 115

= Rs 30245

Therefore ,

Selling price of the gadget = Rs30245
