of their total salary together what percent
they spent?
a. 55%
b. 65%
c. 70%
d. 60%​

Answer 1

70%

we know that

let x be their total salary

and A saves 8300RS and b saves 6400

so let

salary of A be x+8300

and salary of B be

x+6400

now

x+8300

now x+6400...........1

x+8400.................2

adding eq 1and 2

2x+(6400)(8300)

= (3200+4150l2

( 32+415)2x thus

447/2=223x

so 223+223/2x

means 223+111.3

334...............3

414+334 /10.

103+83.4/10

t

so

7350/100
