$\huge\mathbb{\pink{QUESTION ♡- }}\star{}$

30,40 ___,60 are in PROPORTION

${\tt{\green{\underline{\underline{\huge{ANSWER:—}}}}}}$

ʟᴇᴛ ᴛʜᴇ ʀᴇǫᴜɪʀᴇᴅ ɴᴜᴍʙᴇʀ ʙᴇ ʏ.

ᴡᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ,

ᴘʀᴏᴅᴜᴄᴛ ᴏғ ᴇxᴛʀᴇᴍᴇ = ᴘʀᴏᴅᴜᴄᴛ ᴏғ ᴍᴇᴀɴ

⟹ 30×60 = 40 × ʏ

⟹ 1800 = 40 × ʏ

⟹ 1800/40 = ʏ

⟹ 45 = ʏ

⟹ ʏ = 45

sᴏ, ᴛʜᴇ ʀᴇǫᴜɪʀᴇᴅ ɴᴜᴍʙᴇʀ ɪs 45
