Answer 1

★ Question ★

1. Find the value of x.

(a) 250% of x is the sum of 350 and 250

(b) x% of 70 is 14

2. An item was sold for Rs 540 at a loss of 5%. What was its cost price?

★ Answer ★

1. (a) 250x/100 = 350 + 250

» x = 600 × 100/250

» x = 240

• Here, the value of the x is 240.

(b) x/100 × 70 = 14

» x = 14 × 100/70

» x = 20

• Here, the value of the x is 20.

2. Given, S.P of the Item = ₹540

Given, Loss% = 5%

Loss% = (Loss/C.P) × 100

» Loss% = (C.P - S.P/C.P) × 100

» (C.P - 540/C.P) × 100 = 5

» (C.P - 540/C.P) = 5/100

» (C.P - 540) (100/5) = C.P

» 20(C.P - 540) = C.P

» 20 C.P - C.P = 10800

» 19 C.P = 10800

» C.P = ₹ 568.42

So, the cost price of the item is ₹ 568.42.
