Answer:
1st solve:-
Let the salary before the increment be Rs.100. Then,
Increase in salary =Rs.10
∴ Increased salary =Rs.(100+10)=Rs.110
If increased salary is Rs. 110, original salary =Rs.100
If increased salary is Rs. 154000, original salary =Rs.( 110/100×154000)=Rs.140000
Hence, the salary of the man before increment was Rs.140000.
2nd solve:-
On Sunday, people went to the Zoo= 845
On Monday, people went to the Zoo = 169
Number of decrease in the people
= 845 – 169 = 676
Decrease percent =676/845×100=80%
Hence the decrease in the number of people visiting the Zoo is 80%.
3rd Solution:-
No. of articles = 80
Cost Price of articles = Rs. 2,400And Profit
= 16%
∵ Cost price of articles is Rs.100, then selling price = 100 + 16 = Rs.116
∴ Cost price of articles is Rs.1, then selling price = 116/100
∴ Cost price of articles is Rs.2400, then selling price = 116/100×2400=Rs. 2784
Hence, Selling Price of 80 articles = Rs.2784
Therefore Selling Price of 1 article
= 2784/80=Rs. 34.80
4th solve:-
Therefore Total Cost Price = 15500 + 450 = Rs.15,950
Let C.P be Rs.100, then S.P. = 100 + 15
= Rs.115
∵ When C.P. is Rs.100, then S.P. = Rs.115
∴ When C.P. is Rs.1, then S.P. =115/100
∴ When C.P. is Rs.15950, then S.P.
= 100/115×15950=Rs. 18,342.50
I hope this helps you and there are all 4 question solution.
