Answer 2

Answer: Their savings are 48000, 51000 and 36000.

Step-by-step explanation:

Since,  The percentages of  their expenses are 75%, 80% and 90% respectively.

⇒ The percentages of  their savings are 25%, 20% and 10% respectively.

Since,  the ratio of their savings is  16 : 17 : 12,

Let their savings are 16x, 17x and 12x,

Where x is any number.

Since, 25 % of Ramesh's income = 16x

⇒ Ramesh's income = $\frac{16x\times 100}{25}=64x$

20 % of Suresh's income = 17x,

⇒ Suresh's income = $\frac{17x\times 100}{20}=85x$

And, 10 % of Preeti's income = 12x

⇒ Preeti's income = $\frac{12x\times 100}{10}=120x$

Hence, the total income of  Ramesh, Suresh and Preeti = 64x + 85x+120x=269x

According to the question,

269 x =  8,07,000

⇒ x = 3000.

Hence, their saving are 48000, 51000 and 36000.
