Answer 1

Step-by-step explanation:

Let the price be x

price+(price)(20)/100=SP

x+(x)(20)/100=SP_eq1

price+(price)(7/5)=SP+12

x+(x)(7/5)=SP+12

x+(7x)/5–12=SP_eq2

eq1=eq2

x+(x)(20)/100=x+(7x)/5–12

x+(2x)/10=(12x)/5–12

12x/10=(12x-60)/5

6x/5=(12x-60)/5

6x=(12x-60)/5×5

6x=12x-60

6x-12x=—60

-6x=—60

x=—60/—6

x=10Rs.

Substitute the value of x in eq1

x+(x)(20)/100=SP

x+(2x)/10=SP

12x/10=SP

12×10/10=SP

SP=12Rs.
