**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
