   x = 2,00,000
   
   
7. The income of a property dealer remains unchanged though the rate of commission is increased from 8% to 10%. The percentage change in the value of business is

   D. 28%
   
   Answer

   B. 20%
   Explanation:
   Let initial value of business = Rs 100
   income from commission = 8/100 % 100 = Rs 8
   Now income remain unchanged, but rate changed to 10%. Let new value of business = Rs x
   then, 10/100 * x = 8, x = Rs 80
   % change = (100-80)/100 * 100 = 20%
   
   
8. A fruit vendor buys certain numbers of apples at 20 per Rs 15 and twice this number of apples at 30 per Rs 20. He sells all the apples at 24 per Rs 18. At most what discount percentage can he offer so that he does not has a loss?
   A. 8%
   B. 7.41%
   C. 7.14%
   D. 5%
   
   Answer

   B. 7.41%
   Explanation:
   take lcm(20,30,24) = 120
   let 120 apples at 20 for Rs 15, then cost of 120 apples is 90.
   now twice the number at 30 for Rs 20, so cost of 240 apples is 160.
   Total cost of 120+240(360) apples is 90+160 = 250.
   he sells 360 apples at 24 for Rs 18, therefore, S.P of 360 is 270.
   Now if he wants no loss, then at most he can sell 360 apples at 250(at which he bought)
   so d% = 20/270 * 100
   
   
9. The marked price of an article is 30% higher than the cost price. It is sold after allowing 10% discount to the customers, then the gain percent is

   Explanation:
   Use M.P. = (100+p%)/(100-d%) * C.P.
   130/100 * C.P. = (100+p%)/(100-10%) * C.P.
   
   
10. A solution contains alcohol, acid and water in the ratio 1 : 2 : 3, while another solution contains these in the ratio 2 : 3 : 4. If both the solutions are mixed in the ratio 5 : 9, then the percentage of acid in the final solution is
    A) 33 1/3 %
    B) 33%
    C) 50%
    D) 28%
    
    Answer

    A) 33 1/3 %
    Explanation:
    we have to find % of acid.
    In first sol, acid : (alc+water) = 2 : (1+3) = 1 : 2
    In second sol, acid : (alc+water) = 3 : (2+4) = 1 : 2
    final ratio of acid : (alc+water) = (1/3 * 5 + 1/3 * 9) : (2/3 * 5 + 2/3 * 9) = 1 : 2
    % of acid = 1/3 * 100
