ʟᴇᴛ's ᴀssᴜᴍᴇ

• ᴛʜᴇ ɴᴜᴍʙᴇʀ ᴏғ ɢɪʀʟs = x
• ᴛʜᴇ ɴᴜᴍʙᴇʀ ᴏғ ʙᴏʏs = y

Tʜᴇɴ,

Tʜᴇɴ,Tᴏᴛᴀʟ sᴛᴜᴅᴇɴᴛs = x + y = 10 ........( 1 )

ᴛʜᴇ ɴᴏ. ᴏғ ɢɪʀʟs = ɴᴏ. ᴏғ ʙᴏʏs + 4x = y + 4 ......( 2 )

Pᴜᴛ ᴛʜɪs x ᴠᴀʟᴜᴇ ɪɴ ᴇquation ( 1 ), ᴡᴇ ɢᴇᴛ

y + 4 + y = 10

⟹ 2y + 4 = 10

⟹ 2y = 10 - 4

⟹ 2y = 6

⟹ y = 6/2

⟹ y = 3

Sᴏ ʏ = 3 ᴛʜᴇɴ

x + y = 10 ʙᴇᴄᴏᴍᴇs

⟹ x + 3 = 10

⟹ x = 10 - 3

⟹ x = 7

So,

• ɴᴜᴍʙᴇʀ ᴏғ ɢɪʀʟs = 7
• ɴᴜᴍʙᴇʀ ᴏғ ɢɪʀʟs = 7ɴᴜᴍʙᴇʀ ᴏғ ʙᴏʏs = 3
