Question

The marked price of an article is Rs
740. After two successive
discount
of 15% and x%, it is sold for Rs.
566.10. What is the value of x ?​

Answer 1

Step-by-step explanation:

sp=mp(1-d1%)(1-d2%)

566.1 = 740(1-15%)(1-x%)

566.1 = 740 x .85x(1-x%) , as 1-.15=0.85

566.1/(740 ×.85) =(1-x%)

0.9 = 1-x%

x=0.1×100

x=10%
