Answer 1

Answer:

8) x-4 9) 6

Step-by-step explanation:

8) Radha's age = x ( GIVEN )

Leela's age = x-4

Leela is younger than Radha by 4 years so we subtract 4 with x

9) Let's take number of laddus = x

Number of laddus given = 1

Number of remaining laddus = 5

x = Total number of laddus

x = Number of given laddus + Number of remaining laddus.

x = 1+5

x = 6
