Question

Can you answer this? total salary of three persons a,b and c is rs. 1,44,000. they spend 80%, 85% and 75% respectively. if their savings are in the ratio 8 : 9 : 20, find c\\\'s salary. (a) 48000 (b) 64000 (c) 40000 (d) 32000

Answer 1

Total salary = 144000
savings percentage of A = 100-80=20%
savings  percentage of B =100-85=15%
savings percentage of C = 100-75=25%
savings of A =8x
Savings of B= 9x
Savings of C = 20x
20% × A salary /100= 8x         a's salary = 100/20×8x = 40x
15% × B salary /100= 9x         b's salary = 100/15×9 x = 60x
25%of C salary /100= 20x       c's salary = 100/25×20x = 80x

40x + 60x+ 80x = 144000
180x = 144000
x = 800


So C's salary = 80 × 800 = 64000


hope it helps
