Chapter 4: Algebra Puzzle

Let a represent the star

Let b represent the umbrella

Let c represent the ice-cream

3a= 42

so, a=42/3= 14

a=14

a+2b=34=14+2b=34

34-14=2b=20

so, b= 20/2=10

2a+c=36

(14x2)+c=36=28+c=36

36-28=c=8

c=8

Ans: a=14

b=10

c=8

Let a represent the Flower

Let b represent the Apple

Let c represent the Pen

3a=69

a=69/3=23

3a+b=80=(3x23)+b=69+b

80-3a=80-69=b=11

2a+c=49=(2x23)+c=46+c

49-2a=49-46=c=3

Ans: a= 23

b=11

c= 03
