Solution:
1.
Explanation
Let the number be x. Then,
(4/5 x)-(65% of x)= 21 => 4x/5-65x/100=21 => 4x/5-13x/20=21
=> 16x-13x=420 =>3x=420 ?x=140.
Required number = 140.

2.
Explanation
Required % = (120/90*100)%= 400/3%

3.
Explanation
Required % = (5/1000*100)%= 1/2%=0.05%

4.
Explanation
Required % = (150/3500*100)%= 30/7%

5.
Explanation
B's salary is less than that of A by is less than that of a by {R/((100+R) )*100}%
= {20/((120) )*100}% = 50/3%

6.
Explanation
B's salary is more than that of A by {R/((100-R) )*100}%
= {25/((100-25) )*100}% = (25/75*100)=100/3%

7.
Explanation
Reduction % in consumption = {R/((100+R) )*100}%(20/120*100)%
= 50/3%

8.
Explanation
Increase % in consumption = {R/((100-R) )*100}% = {10/((100-10) )*100} = 100/9%

9.
Explanation
Let originally revenue obtained by Rs. x.
New revenue = (Consumption * Tax)
= (115% of 80% of Rs. x) = Rs(115/100*80/100*x)=Rs.92x/100
= 92% of the original.
Hence, the revenue is decreased by 8%.

10.
Explanation
Population after 2 years =  {176400 * (1+5/100)2 }
176400* 21/20*21/20=194481
