IBPS RRB OS-1 Paid Test 9

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

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

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

Required difference= Rs [(8% of 5.25)-(6% of 5.25)] lakhs

 = Rs 2% of 5.25 lakhs

= Rs 10500

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

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%

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

Loss on furniture= 60000+6500-55000

  = Rs 11500

Loss on Television= Rs 3000

Then Required ratio=11500:3000

=23:6

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%

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
