Answer:

HEY ,...HERE IT GO.....

ɢɪᴠᴇɴ -----

ꜱ.ᴩ. =258

ᴩʀᴏꜰɪᴛ ᴏɴ ᴛʜɪꜱ ꜱ.ᴩ. = 20%

ᴛʜᴇ ꜱᴩ ᴏɴ ᴡʜɪᴄʜ ᴛʜᴇ ɢᴀɪɴ ɪꜱ 40% = ???

ꜱᴏ ꜰɪʀꜱᴛ ᴡᴇ ʜᴀᴠᴇ ᴛᴏ ꜰɪɴᴅ ᴛʜᴇ ᴄ.ᴩ.

ɴᴅ ᴡᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ

ꜱᴏ ,

ᴄ.ᴩ = 258 × 100/100 +20

= 258 × 0.084

= 214.9999

= 215

ɴᴏᴡ ᴡᴇ ꜰɪɴᴅ ᴛʜᴀᴛ ꜱ.ᴩ. ᴡʜᴇɴ ᴡᴇ ᴇᴀʀɴ 40 % ᴩʀᴏꜰɪᴛ

ᴡᴇ ᴄᴀɴ ᴅᴏ ɪᴛ ʙy ᴛᴡᴏ ᴍᴇᴛʜᴏᴅ .

ᴏɴᴇ ᴜꜱɪɴɢ ᴛʜɪꜱ ꜱᴀᴍᴇ ꜰᴏʀᴍᴜʟᴀ ᴩᴜᴛᴛɪɴɢ x ᴏɴ ᴛʜᴇ ᴩʟᴀᴄᴇ ᴏꜰ ꜱ.ᴩ.

215 = x * 100/100 + 40

215. = x * 0.715

215 /0.715 = x

x = 300.69

ᴏʀ

ꜱ.ᴩ. = ₹ 301

2ɴᴅ ᴍᴇᴛʜᴏᴅ ---

40 % ᴄ.ᴩ. = 215 × 40 /100

= ₹86

ᴀꜱ ᴡᴇ ᴋɴᴏᴡ -

ꜱ.ᴩ. = ᴄ.ᴩ. + ɢᴀɪɴ

= 215 +86

= ₹301
