Raise your hand if math was your most feared subject in school. In fact it was; It required dedication not only to study but also to extreme practice. However, mathematics was not as challenging from the beginning as it was when they welcomed the English alphabet. When these alphabets formed equations, they added additional complications to the topic. Yes, we are talking about algebra.
However, there were some kids in class who always got excellent grades in algebra. Were you one of them?
Let’s find out with these interesting mathematical riddles!
Mathematical riddle 1:
A chocolate bar costs c pence and a drink costs d pence. Write an expression for the cost of 2 chocolate bars and 2 drinks.
Mathematical riddle 2:
Tom is a window cleaner. Use the following formula to calculate the amount to charge your clients:
Fee = £20 + 4n
Where n is the number of windows a house has.
If a house has 7 windows, how much would Tom charge?
Mathematical riddle 3:

ANSWERS:
Maths Riddle 1: A bar of chocolate costs c pence and a drink costs d pence. Write an expression for the cost of 2 chocolate bars and 2 drinks.
Answer:
The equation would be, 2c+2d.
Explanation:
The chocolate bars will cost 2 lots of c. This can be written as 2c, and 2 drinks will cost 2 lots of d. This can be written in 2d.
Mathematical riddle 2:
Tom is a window cleaner. Use the following formula to calculate the amount to charge your clients:
Fee = £20 + 4n
Where n is the number of windows a house has.
If a house has 7 windows, how much would Tom charge?
Answer:
£48.
Explanation:
We know that n=7. The question requires the substitution of 7.
Carry=£20+4×7
Fee = £48
Carry=£48
Mathematical riddle 3:
Harry’s dad is 4 times older than Harry. In 14 years, Harry’s father will be twice his age.
What is the sum of Harry’s current age and Harry’s father’s current age?
Answer:
35
Explanation: Suppose Harry’s age is now
x
- x. So Harry’s father’s age is
4x
4x.
In
14
In 14 years Harry’s age will be
x + 14
x+14 and Harry’s father’s age will be
4x + 14
4x+14.
Since we know that Harry’s father’s age will be twice Harry’s age, we can write
4x+14=2(x+14)
4x+14=2(x+14)
So, do you consider yourself good at algebra? How well would you rate your skills?
