The ratio of the ages of ramu and his sister is 3:4 . If the age of his sister is 36,how old is ramu?
ʀᴀᴍᴜ : sɪsᴛᴇʀ
3 : 4
4x=20
x = 20/4
x =5
ᴀɢᴇ ᴏғ ʀᴀᴍᴜ =3x
3×5
= {15 ʏᴇᴀʀs}
ramus age --- 3x
sister's age --- 4x
but 4x = 36
x = ...
carry on.
To find Ramu's age, we need to use the given ratio and the age of his sister.
Given that the ratio of the ages of Ramu and his sister is 3:4, we can set up a proportion:
3/4 = x/36
To solve for x (Ramu's age), we can cross-multiply:
4x = 3 * 36
4x = 108
Now, divide both sides of the equation by 4, to isolate x:
x = 108/4
x = 27
Therefore, Ramu is 27 years old.
