Answer 1

Answer:

1500

Step-by-step explanation:

Let the expenses of A, B and C be Rs. 8x, Rs. 5x and Rs. 2x respectively. Given, 2x = 2000

⇒x=Rs.1000

⇒ B's expenses =5×Rs.1000=Rs.5000,

A's expenses =Rs.8000

Given, B's saving =Rs.700

⇒ B's income =Rs.5000+Rs.700=Rs.5700

Given, A's income : B's income = 5 : 3

⇒5700A’s income=35

⇒ A's income =35×Rs.5700=Rs.9500

∴ A's savings =Rs9500−Rs.8000=Rs.1500
