Answer 1

Answer:

(a) 7y-4

(b)11y+11

Step-by-step explanation:

tinkoo is 'y' years old

Raghu is 4y

bittoo is y-4

(a) sum of present ages of raghu, tinkoo and bittoo

y+4y+y-4

7y-4

(b) sum of the ages of raghu, tinkoo and bittoo after 5 years

After 5 years,

tinkoo is 'y+5' years old

Raghu is 4y+5

bittoo is y-4+5=y+1

y+5+4y+5+y+1

11y+
