Question

सलमा अपनी बहन रेशमा से 10वर्ष बड़ी है 4वर्ष पहले सलमा की आयु रेशमा की आयु की 2 गुना थी । दोनों की वर्तमान आयु बताओ​

Answer 1

Answer:

salma;:x

reshma:y

x-y=10 .........1

x-4=(y+4)2

x-4=2y+8

x-2y=12..........

1 and x-y-10=x-2y-12

so,

y=5

x=15

Answer 2

The present age of Reshma and Salma are 14 years and 24 years respectively

Step-by-step explanation:

Let the present age of Reshma be x

We are given that Salma is 10 years older than Reshma

Salma's present age=x+10

Reshma's age 4 years ago = x-4

Salma's age 4 years =x+10-4=x+6

4 years ago Salma's age was twice the age of Reshma

$x+6=2(x-4)\\x+6=2x-8\\x=14$

Salma's present age = x+10=14+10=24 years

Reshma's present age =x = 14 years

Hence The present age of Reshma and Salma are 14 years and 24 years respectively
