Question

Sam saved ₹20000 every month when his monthly income was ₹50000. If he retained the same ratio of his income to savings after getting an increment of ₹5000 to his monthly income, what amount did he save every month after getting the increment?

Answer 1

sᴏʟᴜᴛɪᴏɴ:

ᴍᴏɴᴛʜʟʏ sᴀʟᴀʀʏ ᴏғ ᴀ ᴘᴇʀsᴏɴ = ʀs. 12000

ᴍᴏɴᴛʜʟʏ ᴇxᴘᴇɴᴅɪᴛᴜʀᴇ = 8500

sᴀᴠɪɴɢ ᴏғ ᴛʜᴇ ᴘᴇʀsᴏɴ = 12000 - 8500 = ʀs. 3500

(ɪ) ʀᴀᴛɪᴏ ʙᴇᴛᴡᴇᴇɴ sᴀʟᴀʀʏ ᴀɴᴅ ᴇxᴘᴇɴᴅɪᴛᴜʀᴇ

12000:8500=\ғʀᴀᴄ{12000}{8500}=\ғʀᴀᴄ{120}{85}=\ғʀᴀᴄ{24}{17}=24:1712000:8500=850012000=85120=1724=24:17

(ɪɪ) ʀᴀᴛɪᴏ ʙᴇᴛᴡᴇᴇɴ ᴇxᴘᴇɴᴅɪᴛᴜʀᴇ ᴀɴᴅ sᴀᴠɪɴɢs

8500:3500=\ғʀᴀᴄ{8500}{3500}=\ғʀᴀᴄ{85}{35}=\ғʀᴀᴄ{17}{7}=17:78500:3500=35008500=3585=717=17:7

(ɪɪɪ) ʀᴀᴛɪᴏ ʙᴇᴛᴡᴇᴇɴ sᴀᴠɪɴɢs ᴀɴᴅ sᴀʟᴀʀʏ

3500:12000=\ғʀᴀᴄ{3500}{12000}=\ғʀᴀᴄ{35}{120}=\ғʀᴀᴄ{7}{24}=7:243500:12000=120003500=12035=247=7:24

like these you can do
