3. What is the Ratio of Rs. 50 and Rs. 10 ……5:1………

4. 5 : 6 :: …75…. : 90  (5x15,6 x 90)

5. 3 : 6 :: 12  …24……. (3x4, 6 x 4)

6. 1: 2 :: 4 :: …8…….. (1x4, 2 x 4)

7. 3 : 4 ::  …24 … 32    ( 4x8, 3 x8)

8. 40 % of a number is 800 then find the number. 
   100/40 x800 =2000

9. P : Rs. 8000       R 10%    T = 3 ears find simple interest    8000 x 10 x 3/100 =2400

10.  P : Rs. 8000       R 10%    T = 2 years find Compound interest …..8000x10x2/100 = 1600
