Let the amounts invested in 2010 in companied A and B be Rs 14x and Rs 5x respectively.
Then interest received after one year from company A= 7% of 14x
= Rs 98x/100
And interest received after one year from company B= 10% of 5x
= Rs 50x/100
Hence required ratio= (98x/100):( 50x/100)
= 49:25
Question 2:
Rs 13.5 lakhs 13.5 लाख रुपये
Rs 15.4 lakhs 15.4 लाख रुपये
Rs 14.1 lakhs 14.1 लाख रुपये
Rs 18.1 lakhs 18.1 लाख रुपये
Rs 12.1 lakhs 12.1 लाख रुपये
Total amount received from company B after one year=Rs (10+10% of 10) lakhs
= Rs 11 lakhs
Now total amount received from company A after one year on investment of Rs 11 lakhs in 2012= Rs (11+10% of 11) lakhs
= Rs 12.1 lakhs
Question 3:
16 lakhs 16 लाख
62 lakhs 62 लाख
5 lakhs 5 लाख
16 lakhs 16 लाख
10 lakhs 10 लाख
Let Rs x be the amount invested by the company
A. Then total amount invested by the company B be Rs (40-x) lakhs
Thus, 15% of x+10% of (40-x) = 4.5
15% of x- 10% of x+10% of 40= 4.5
5% of x+4= 4.5
5% of x=0.5
x=10 lakhs
Question 4:
Rs 18090
Rs 19070
Rs 10380
Rs 10500
Rs 15700
Required difference= Rs [(8% of 5.25)-(6% of 5.25)] lakhs
= Rs 2% of 5.25 lakhs
= Rs 10500
Question 5:
Rs 290400
Rs 249070
Rs 235900
Rs 214400
Rs 755700
Total amount received from company A in 2007= Rs [16+(5% of 16) lakhs
= Rs 16.8 lakhs
In 2008, Total amount received from company A = Rs [16.8+ (8% of 16.8) lakhs
= Rs 18.144 lakhs
Now interest received on investment during the period of two years= Rs (18.144-16) lakhs
=Rs 2.144 lakhs
=Rs 214400
Question 6:
246.5%
203.5%
118.5%
257.5%
157.5%
Selling price of the Washing Machine= (Cost price +Transportation cost+ profit)
=35000+4000+2500
=Rs 41500
Now Cost price of the Television= Selling price +loss
= 32000+3000
= Rs 35000
Required percentage=41500/35000×100=118.5%
Question 7:
Rs 236790
Rs 225720
Rs 298620
Rs 266220
Rs 246970
Given that Cost price of Bike= Rs 1,80,000 and Transportation cost= Rs 18000
Then total cost price of the bike=180000+18000=Rs 198000
Since the profit is 14%, Selling price of the bike= 198000+14% of 198000
= 198000+ 27720
= Rs 225720
Question 8:
23:6
15:8
14:9
24:9
24:5
Loss on furniture= 60000+6500-55000
= Rs 11500
Loss on Television= Rs 3000
Then Required ratio=11500:3000
=23:6
Question 9:
93.68%
83.68%
68.68%
95.68%
85.68%
Selling price of the Fan= (Cost price + transportation Cost)× 95/100
= 2500×95/100
= Rs 2375
And selling price of Furniture= Rs 55000
Required percentage= [(55000-2375)/55000]×100= (52625/55000)×100
= 95.68%
Question 10:
Rs 26890
Rs 21500
Rs 26870
Rs 28930
Rs 21580
Selling price of the Kitchen items= (Cost price +Transportation cost+ profit)
=52000+5000+6000
=Rs 63000
Selling price of the Washing Machine= (Cost price +Transportation cost+ profit)
= 35000+4000+2500
= Rs 41500
Required difference= 63000-41500=Rs 21500
