Answer i by method 1.
10% more than 80=110% of 80=110/100 × 80=11×8=88.
Answer ii by another method 2.
5% of 150=5/100 × 150=15/2=7whole 1/2=7.5.
Now, 5% of 50 less than 50=50-7.5
=42.5 or 85/2=42whole 1/2

Question:-
Find the number which is
Find the number which is (i) 10% more than 80.
Find the number which is (i) 10% more than 80. (ii) 5% less than 150.
Solution:-
(a) 10% more than 80.
The required number = 80 + 10% of 80
[tex] = 80 \times \frac{10}{100} \times 80 = 80 + 8 = 88[/tex]
Hence the required number is 88
(ii) 5% less than 150.
The required number = 150 - 5% of 150
[tex] = 150 - \frac{5}{100} \times 150 = 150 - \frac{15}{2} \\ \\ = \frac{300 - 15}{2} = \frac{285}{2} = 142.5[/tex]
Hence the required number is 142.5
