Answers
1.) ¾ ×100
=75%
2.) (100-85)%
=15%
3.) 25% of x=100
Or, 25/100 × x =100
Or, x/4=100
So, x=400
4.) Ram:shyam =5:3
Let ram gets 5x pens
Shyam gets 3x pens
So, 5x+3x=200
So x=25
Shyam will get 3×25=75 pens
5) 13/100 ×130000
=16900
6.) Passing marks was= 86+4=90
Let total marks was x
So, x × 30/100=90
X=300
7.) Absent= 60/100 ×100
=60 students
8.) Cost price=80rs
Selling price=90rs
Profit=(90-80)=10rs
So profit percentage = 10/80 × 100
=12.5%
9.) 1 kg=1000gm
8/100 × 1000 gm
= 80gm
10) 125% = 125/100 = 5/4
11) 400/500 ×100
=80%
12.) 2/5 ×100
=40%
13.) Loss =(5000-4500)
=500rs
500/5000 ×100
=10% loss
14.) x/12=12/x
=x^2= 144
X=12
15.) 1000×5×2/100
=100rs
- Let cp=x
So x × 110/100 =990
X=900
17.) Let the number is x
X+ x×60/100=96
X=60
18.) 90/180 ×100 =50%
19.) 7000× 115/100
=8050 rs
20.) 4.5/100 × 200
=45/1000 ×200
= 9
21.) 50+30=80 rs
22.) 10/100 × x = 150
X=1500
23.) Cp of one orange =12rs
Cp of 12 oranges= 12×12=144rs
24.) Let marked price =x
X×90/100=150
X=166 2/3
25.) 4/5×100
=80%
