Shiva has decided to start a business for that he wants to buy some furniture – table, chair, air conditioners. He also wants to buy a few computer system which will include monitor, CPU, Keyboard and mouse. The cost of each table is 13.5 times the cost of a mouse and the cost of a chair is 3/5 of the cost of a table. The cost of an air conditioner is 5 times the cost of a chair. The cost of a monitor is 20% more than the cost of a chair, a CPU costs Rs. 1500 more than a table and the keyboard costs 4 times a mouse. The cost of a mouse is Rs. 1000.

- Find the cost of the computer system, if the cost of a keyboard and a mouse increases by 20% and 15% respectively,(considering the same cost of CPU and monitor).?
Rs.28,550Rs.30,670Rs.21,460Rs.45,000Rs.10,452Option B

20% of Keyboard = 4000*(120/100) = Rs.4800

15% of Mouse= 1000*(115/100) = Rs.1150

CPU = Rs.15,000 Monitor = Rs.9,720

Addition we get the cost of computer system = Rs.30,670 - It was initially decided that 4 air conditioners will be installed but later only 3 air conditioners and a fan were installed. If the cost of a fan is 1/10 of the cost of an air conditioner, what was the total cost incurred?
Rs.3,02,315Rs.2,32,000Rs.1,50,000Rs.1,25,550Rs.2,30,450Option D

Cost of a fan = 40500/10 = Rs.4050

Now, cost of three AC and one fan = 3*40500 + 4050 = 121500 + 4050 = Rs.1,25,550 - Shiva bought 1 table, 1 chair and 1 desktop for himself. What was the total cost incurred to him?
Rs.52,250Rs.32,440Rs.51,320Rs.18,000Rs.60,000Option C

Total cost = 13500 + 8100 + 1000 + 4000 + 9720 + 15000

= Rs. 51,320 - What will be the total cost of 1 table and 2 chairs together?
Rs.30,500Rs.32,540Rs.20,000Rs.15,560Rs.29,700Option E

Total Cost = 13500 + (2 * 8100) = Rs.29,700 - Find the ratio of the cost of a CPU to the total cost of a mouse and a keyboard together?
5:24:73:11:62:7Option C

Cost of CPU = Rs.15,000

Cost of mouse and keyboard = Rs.5,000 Required ratio = 15000:5000 = 3:1 - What is the ratio of the total population of Chennai for the years 2002 and 2003 together to the total population of Delhi for the years 2000 and 2001 together?
26:1720:1911:2117:1931:42Option A

Required ratio = (60+70)/(40+45) = 130:85 = 26:17 - What is the per cent rise in the population of Delhi from 2003 to 2004?
50%40%60%30%70%Option B

Percentage rise = [(70-50)*100]/50 = 40% - What is the average population of Chennai for all the given years?
7540655060Option E

Required average = (50+40+60+70+80)/5 = 60lakhs - Find the difference between the total number of population between these two states from all the given years ?
3542504830Option A

Total population in Delhi = 265

Total population in Chennai = 300

Required difference = 300-265 = 35lakhs - The population of Chennai in 2002 is what percent of the total population of Delhi in all the years together? (Rounded off of two digits after decimal)
22.64%15.15%16.67%25.75%33.33%Option A

Required % = 60*100)/(40+45+60+50+70) = (60*100)/265

= 22.64%
