Answer 1

Let the basic price of the refrigerator be x 

Rate of sales tax = 12 % 

Therefore, total price of the refrigerator =

`"Rs"  ("x" + ("x" xx 12)/100)` 

= Rs `(112  "x")/100`

Total cost of refrigerator given= Rs 30,940 

`therefore (112  "x")/100` = Rs 30940

⇒ 112 x = Rs30, 94, 000 

⇒ x = Rs `3094000/112`

⇒ x = Rs 27625

Hence, the basic price of refrigerator = Rs 27,625
