Question

The C.P of deak and chair is rupees 371 if desk cost 12percent more than the chair find C.P of each

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

cost price of desk and chair = Rs 371 (Given)

Define x:

Let the cost of chair be x

Express the cost of desk in x:

The desk costs 12% more than the chair:

12% of x = 0.12x

desk = x + 0.12x = 1.12x

Form equation and solve for x :

The total cost is Rs 371

x + 1.12x = 371

2.12x = 371

x = 371 ÷ 2.12

x = Rs 175

Find the cost of desk and chair:

chair = x = Rs 175

Desk = 1.12x = 1.12(175) = Rs 196

Answer: The chair costs Rs 175 and the desk costs Rs 196

Answer 2

x+x+12/100×x=371( chair is x then desk is x+12/100of x since desk is more by 10 %
x+x+3x/25=371
2x+3x/25=371
50x+3x/25=371
53x=25×371
x=25×371/53
x=175
so, the cost of chair =175
now desk=175×12/100+175
21+175=196
