$\bf{\underline\red{ɢɪᴠᴇɴ\:,}}$

ᴄᴏsᴛ ᴏғ 28 ɢᴇʟ ᴘᴇɴs ᴀɴᴅ 2 ғᴏᴜɴᴛᴀɪɴ ᴘᴇɴ ɪs ₹ 93.5

28ɢᴇʟ + 2 ғᴏᴜɴᴛᴀɪɴ ᴘᴇɴs = 93.5

28 ɢᴇʟ ᴘᴇɴs = ₹?

2 ғᴏᴜɴᴛᴀɪɴ ᴘᴇɴ = ₹?

$\bf{\underline\green{ɪɴ \:ǫᴜᴇsᴛɪᴏɴ\: ᴀs \:ɢɪᴠᴇɴ \: ,}}$

ᴄᴏsᴛ ᴏғ ᴏɴᴇ ғᴏᴜɴᴛᴀɪɴ ᴘᴇɴ = ₹ 32.5

ᴄᴏsᴛ ᴏғ 2 ғᴏᴜɴᴛᴀɪɴ ᴘᴇɴs = ₹(2× 32.5)

⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀⠀⠀=₹65

ᴄᴏsᴛ ᴏғ 28 ɢᴇʟ ᴘᴇɴs = ₹( 65 - 93.5 )

⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ =₹28.5

ᴄᴏsᴛ ᴏғ ᴏɴᴇ ɢᴇʟ ᴘᴇɴ = 28.5/28
