Question 1
Which of the following fraction will give non-terminating decimal on conversion?
83
38
12
714
SOLUTION
Solution : A
Among the options, only 83 is the fraction which will give non-terminating decimal. This is because all other options have denominator having on 2 and 5 as prime factors after standardising.
Question 2
Which one of the following lies between 0.3 and 0.7?
0.2
0.4
0.8
0.9
SOLUTION
Solution : B
Consider 0.9, it is greater than 0.7 as well as 0.3, hence it cannot lie between 0.3 and 0.7. Similarly, 0.2 and 0.8 cannot lie between 0.3 and 0.7.
But, 0.4 is greater than 0.3 and less than 0.7. Hence, it lies between 0.3 and 0.7.
OR
0.2 has 2 tenths, 0.3 has 3 tenths, 0.4 has 4 tenths, 0.7 has 7 tenths, 0.8 has 8 tenths and 0.9 has 9 tenths.
2 tenths<3 tenths<4 tenths<7 tenths<8 tenths<9 tenths
⟹0.2<0.3<0.4<0.7<0.8<0.9
Thus, 0.4 lies between 0.3 and 0.9.
Question 3
If ₹ 70 is distributed equally among 40 poor children, how much will each child get?
