Question

the age of Nandana and Harshit or in the radio 2 : 3 after 15 years the radio of their age will be 3 : 4 find their parents age​

Answer 1

Gɪᴠᴇɴ :-

• The age of Nandana and Harshit or in the radio 2 : 3 after 15 years the ratio of their age will be 3 : 4

ᴛᴏ ғɪɴᴅ :-

• Present ages

sᴏʟᴜᴛɪᴏɴ :-

✚ Let the present age of Nandana be 2x then Harshit be 3x

☞ According to the question

• After 15 years
• Nandana's age = 2x + 15
• Harshit's age = 3x + 15

➪ 2x + 15/3x + 15 = 3/4

➪ 3(3x + 15) = 4(2x + 15)

➪ 9x + 45 = 8x + 60

➪ 9x - 8x = 60 - 45

➪ x = 15

Hence,

• Present age of Nandana = 2x = 30 years
• Present age of Harshit = 3x = 45 years

Answer 2

Hello Friend

Hope this helps you

Present-

let age of Nandana be 2x amd Harshit be 3x.

Ratio = 2:3

After 15 years,

Ratio = 3:4

Age of Nandana and Harshit = 2x + 15 and 3x + 15

Therefore,

2x + 15 = 3x(from 3:4)

x = 15

Also if you use 3x + 15 = 4x

x = 15

therefore,

the present ages of

Nandana = 2x = 2 x 15 = 30

Harshit = 3x = 3 x 15 = 45
