1. (a) ratio = 1 : 20

(b) ratio = 2: 5

(c) ratio = 20 : 1

2. x = 5

3. (a) = 7 / 100

(b) = 3/20

4. (a) = 1 /8

(b) = 3/4

5.

(a ) = 525 %

(b) = 45%

6.

20/100 × 2500 = 500RS

7. 40x / 100 = 500

x = 5000/4 = 1250km

8. 12 x = 48

10x = 480 / 12

= 40Rs

9.

9x = 180

x = 20

measures = 40 , 60 , 80

10.

3/4 x = 18

x = 24

11 .

( 3 × 100 ) / 25 = 12 %

12.

100 - (35+45) = 20%

13 .

I = 900 × 5 × 6 / 100

= 270 RS

14.

8 C = 6S

C= 3S/4

Gain % = (S-C)x100/C

= Sx100/4/(3S/4)

= 100/3

= 33.33 %

15.

I = P×6×10 / 100

= 3P/5

900 = P + 3P/5

900 = 8P /5

P = 562.5 RS

16. (a) = 24

(b) = 24
