*9. A milk man adds 250ml of water to I litre of milk. Find the ratio of water milk.*

*Ans. Quantity of water = 250 lr.,*

*Quantity of milk= 1 litre= 1000ml.*

*Ratio of Milk and Water = 250 : 1000 i.e. 1”4*

*10. Rama’s mother bought 5kg. pulses and 50g chill powder. Find the ratio of weights of chilli powder to pulses. What is the ratio of weights of the pulses to chilli powder?*

*Sol. Weight of pulses = 5kg.*

*Therefore 5 x 1000 Grams=5000grms.*

*Weight of chilli powder = 50 gm.*

*Ratio : 50 : 5000 = 1:100,*

*Ratio of weights of the pulses to chilli powder =100 :1*

*11.Sameera takes 30 minutes to reach school from home. Pradeep takes ½ an hour to cover the same distance. Find the ratio of time taken by Sameera the time taken by Rama.*

*Time taken by Sameera to reach school from home = 30 minutes*

*Time taken by Pradeep to cover the same distance = ½ hour= 30 minutes*

*Ratio of time taken by sameera to the time taken by pradeep= 30 :30 == 1:1*

*12. Rama bought 2 liters of ail and vijay bought 500 ml of oil. Find the ratio of quantities of all bought by Rama to oil bought by vijay.*

*Quantity of oil bought by Rama= 2 liters = 2 x 1000 ml. =2000ml*

*Quantityy of oil bought by Vijayy = 500ml.*

*Ratio : 2000 : 500 == 4 : 1*

*Sum of two numbers: 132. Ratio of two numbers= 5:6 Total =11*

*Value of 11 parts = 132, value of eache part = 132/11 = 12*

*The Ist number = 12 x 5= 60*

*The 2*^{nd}number = 12 x 6 = 72 i.e. two numbers = 60 and 72

*16.If three apples cost Rs. 45/- how much would five apples cost Rs.*

*Three apples cost = Rs. 45/-, i.e. one apple cost = 45/3=Rs.15*
