ANSWERS:
Math Riddle 1:
One-half of the students in a school are girls, and 3/5 of these girls are studying in lower classes. What fraction of girls are studying in lower classes?
Answer 1:
Fraction of girls studying in school = 1/2
Fraction of girls studying in lower classes = 3/5 of 1/2
= 3/5 × 1/2
= (3 × 1)/(5 × 2)
= 3/10
Thus, 3/10 of girls study in lower classes.
Math Riddle 2:
Sam reads three-fifth of 75 pages of his lesson. How many more pages does he need to complete the lesson?
Answer 2:
Sam reads = 3/5 of 75
= 3/5 × 75
= 45 pages.
Sam has to read = 75 – 45.
= 30 pages.
Thus, Sam has to read 30 more pages.
Math Riddle 3:
A herd of cows gives 4 liters of milk each day. But each cow gives one-third of the total milk each day. They give 24 liters of milk in six days. How many cows are there in the herd?
Answer 3:
A herd of cows gives 4 liters of milk each day.
Each cow gives one-third of the total milk each day = 1/3 of 4
Therefore, each cow gives 4/3 of milk each day.
Total no. of cows = 4 ÷ 4/3
= 4 × ¾
= 3
Thus, there are 3 cows in the herd.
Math Riddle 4:
If 312 m of wire is cut from a piece of 10 m long wire, how much of the wire is left?
Answer 4:
The total length of the wire = 10 m
Fraction of the wire cut out = 312 m = 72 m
Length of the wire left = 10 m – 312 m
= [101 - 72] m, [L.C.M. of 1, 2 is 2]
= [202 - 72] m, [101 × 22]
= [20−72] m
= 132 m
= 612 m
How many of them could you guess right? If every riddle had 5 marks, what is your score?
Oh, wait, did we promise not to add the pressure to score on your shoulders?
