Question

Total income of Ramesh, Suresh and Preeti is 8,07,000 rupees. If the percentages of their expenses are 75%,80% and 90%respectively. If the ratio of their savings is 16:17:12, then find the annual saving of each of them. ​

Answer 1

Step-by-step explanation:

let their earnings be x y z respectively

x + y + z = 807000

Their savings are 25% 20% 10% respectively

i.e. 0.25x 0.2 y 0.1z

given

0.25x : 0.2 y : 0.1z = 16 : 17 : 12

let the proportionality constant be k

0.25x = 16k x = 64k

0.2y = 17k y = 85k

0.1z = 12k z = 120k

Now

x + y + z = 807000

269k = 807000

k = 3000

Now the savings are

16k = 48000

17k = 51000

12k = 36000

Their Salaries are

192000 255000 360000 respectively

Their savings are

48000 51000 36000 respectively
