Question 11 of 15

11. Question

Category: New Pattern Quadratic Equations

Quantity I: The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:

Quantity II: Find the speed of a train which passes a tree in 12 seconds. The length of the train is 264m.

Correct

Solution:

I. Let the speed of two trains be 7x and 8x.

400/4=100 8x=100==>x=12.5.

Then speed of first train =7*12.5 =87.5km/hr.

II. Length of the train = 264m.

Time taken to pass the tree = 12 seconds.

Speed of the train = 264/12 m/sec = 22 m/sec = 22 * 18/5 km/hr = 79.2 km/hr.

Incorrect

Solution:

I. Let the speed of two trains be 7x and 8x.

400/4=100 8x=100==>x=12.5.

Then speed of first train =7*12.5 =87.5km/hr.

II. Length of the train = 264m.

Time taken to pass the tree = 12 seconds.

Speed of the train = 264/12 m/sec = 22 m/sec = 22 * 18/5 km/hr = 79.2 km/hr.

Question 12 of 15

12. Question

Category: New Pattern Quadratic Equations

Quantity I: A and B started a business by investing Rs. 20000 and Rs. 35000 respectively. Find the share of B out of an annual profit of Rs. 3520.

Quantity II: X and Y invested in a business. Their profit ratio is 2:3. If X invested Rs. 4000. Find the amount invested by Y?

Correct

Solution:

I Ratio 20:35=4:7 11 == 3520 7 ?==>Rs2240.

II 4000/y = 2/3 y = 6000.

Incorrect

Solution:

I Ratio 20:35=4:7 11 == 3520 7 ?==>Rs2240.

II 4000/y = 2/3 y = 6000.

Question 13 of 15

13. Question

Category: New Pattern Quadratic Equations

Quantity I: The age of P is twelve times that of her daughter Q. If the age of Q is 3 years, what is the age of P? Quantity

II: The ratio between the present ages of A and B is 2:3. 4 years ago the ratio between their ages was 5:8. What will be A‘s age after 7 years?

Correct

Solution:

I Ratio P:Q 12:1 1…….== 3 12 ? == 12*3 =36

years.

II (5x+4)/(8x+4) =2/3 15x+12 = 16x+8 x=4.

A‘s age 4 yrs ago 5*4=20

Then A‘s age after 7yrs is 20+4+7=31yrs

Incorrect

Solution:

I Ratio P:Q 12:1 1…….== 3 12 ? == 12*3 =36

years.

II (5x+4)/(8x+4) =2/3 15x+12 = 16x+8 x=4.

A‘s age 4 yrs ago 5*4=20

Then A‘s age after 7yrs is 20+4+7=31yrs

Question 14 of 15

14. Question

Category: New Pattern Quadratic Equations

Quantity I: The difference between SI and CI compounded annually on a certain sum of money for 2 years at 8% per annum is Rs. 12.80. Find the principal. Quantity

II: A sum fetched a total simple interest of Rs. 800 at the rate of 8 %per annum in 5 years. What is the sum?

Correct

Solution:

I SI-CI=Pr2/100. P*82/100=12.8 64P/(100*100)=12.8 P=Rs2000.

II SI=Pnr/100 800=P*8*5/100 P=800*100/40 =Rs2000.

Incorrect

Solution:

I SI-CI=Pr2/100. P*82/100=12.8 64P/(100*100)=12.8 P=Rs2000.

II SI=Pnr/100 800=P*8*5/100 P=800*100/40 =Rs2000.
