Answer 1

q.

let number be x and other is y
x = 3/5 y
sum=88
x+y=88
3y/5 +y =88
3y + 5y/5 =88
8y/5 =88
y=88×5/8
y=11×5
y=55
x=3/5×55
x=3×11=33
x=33,y=55

r. let number be x
fifth part = x/5
increased by 5 = x/5 +5
fourth part = x/4
decrease by5 = x/4 -5
x/5 + 5= x/4 -5
x/4 -x/5 = 10
5x-4x/20 =10
x/20=10
x=200 is answer

S. 2tables + 8chairs =2200
table = 150+chair
2(150+chair) +8chair=2200
300+2chair +8chair =2200
10chair=2200-300
10chair=1900
chair=190
table=150+chair
table =150+190
table=340
