Now, S.P. = Rs 130, C.P. = Rs 100

∴ Profit% = 30%

If the total interest accrued in one yearwas Rs. 3200 and The amount invested in scheme C was 150% of the amount invested in scheme A and 240% of the amount invested in scheme B, what was the amount invested in scheme B ?

Solution:

Ratio of Nikhil's investment in difference schemes

= 100 : 150 x 100 /240 : 150 = 8 : 5 : 12

Now, according to the question,

8K x 10 /100 + 5Kx 12/ 100 + 12K x 15 /100 = 3200

or, 80K + 60K + 180K = 3200 x 100

or, 320K = 3200x 100

or K = 1000

∴ Amount invested in scheme B = 1000 x 5

= Rs 5000

QUESTION: 14

**In the following questions two equations numbered I and II are given. You have to solve both the equations and**

I. 3x - 2y = 10

II. 5x - 6y = 6

Solution:

By equation I � 3 - equation II,

9x - 6y - 5x + 6y = 30 - 6

From equation I,

3 � 6 - 2y = 10

⇒ 2y = 18 - 10 = 8

⇒ y = 4

Physics, Chemistry and Biology group = 98

Maths = 95

Social Science = 95.5

Vernacular group = 95

English group = 96 + x/ 296 + x2

Now, final score = 98 + 95 + 95.5 + 95 +96 + x/2598 + 95 + 95.5 + 95 +96 + x/25

⇒ 96 = 767 + (96 + x)10767 + (96 + x)10 = 863 + x10863 + x10
