(ii) What is the ratio of Kuzhali’s savings to that of others?

(iii) How much is Iniya’s savings?

(iv) Find the total amount of savings of all your friends?

(v) Ruby and Kuzhali save the same amount. Say True or False.

Answer 1

(i) Ratio of Ruby’s saving to that of Thasnim’s

= Ruby’s saving/ Thasnim’s saving 

= (5×100)/(4×100) = 5/4 = 5:4

Ratio of Ruby’s saving to that of Thasnims = 5 : 4

(ii) Ratio of Kuzhali’s savings to that of others

= kuzhali’s saving/others saving 

= (5×100)/(19×100) = 5/19 = 5:19

Ratio of Kuzhali’s saving to that of others = 5 : 19

(iii) Iniya’s saving = 3 × 100 = ₹ 300

(iv) Saving of all the friends = (5 + 7 + 4 + 5 + 3) × 100 = 24 × 100 = ₹ 2400.

Total savings = ₹ 2400

(v) True.
