chen donates 15% of his current salary to charity. if his pay is increased by 10% and he still donates 15% of his salary by what % do his charity contributions increase?

• If initial salary is x, then
  initial charity amount = 0.15x
  new charity amount = 1.1*0.15*x = 0.165x
  
  % increase in charity = 100*0.015x/0.15x = 10%

• let chen salary be rs 100, so intial donates rs 15(i.e 15%of his salary),
  After increment of 10 % his new salary is rs. 110. so 15 % of rs110 is Rs16.5.
  %increase in salary is ((16.5-15)/15)*100= 10%...... so ans is 10%..........

• let his salary be 100.
  15% of 100 is 15 used for his charity.
  after 10% increase of his pay,it comes 16.5 rs.
  % inc =(16.5-15)/15 * 100 = 10%
