The price of a transistor radio is Rs. 1100. The sales tax charged is 7 %. Find the final amount the buyer has to pay.

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Given⫸}}}}}}$

• Price = Rs. 1100

• Tax = 7 %

${\large{\fcolorbox{aqua}{navy}{\fcolorbox{yellow}{blue}{\bf{\color{yellow}{⫷Solution⫸}}}}}}$

Tax in amount

= Rs. (7 % of 1100)

= Rs. $({\frac{7}{1\cancel{00}}}×11\cancel{00})$

= Rs. (7 × 11)

= Rs. 77

Billing amount

= Cost + Tax

= Rs. (1100+77)

= Rs. 1177
