Answer 1

Answer:

C.P of 1st tv set is Rs.17,500 and C.P of 2nd tv set is Rs.12,500

Step-by-step explanation:

Given:

Cost price of 2 tv sets= RS.30,000

Let the C.P of 1 st tv set= Rs.x

So, the C.P of 2nd tv set be Rs.(30000 - x)

For 1st tv set,

Loss =16%

S.P={C.P× (100 - %loss)} /100

      ={x × (100 - 15)} /100

      =85 x/100

For 2nd tv set,

Gain = 19%

S.P= {C.P × (100 +% profit )} /100

     = {(30000 -x) × (100 +19) } /100

      ={ (30000 - x ) ×119} /100

According to question,

S.P of 1st tv=S.P of 2nd tv

85x/100 = {(30000 - x) ×119} /100

85x= 30000 ×119 - 119x

85x +119x=35,70,000

204x=35,70,000

     x = 35,70,000 /204

    x=17500

C.P of 1 st tv set= Rs.17,500

C.P of 2 nd tv set = 30,000 - 17,500

                             =12,500 Rs.
