a) Rs. 229.90

b) Rs. 299.20

c) Rs. 276.75

(7-10)Study the pie–chart carefully and answer the questions based on it. Percentage of student enrolled in different game classes in a school

Total number of student = 3600

7) The number of student enrolled in cricket classes is what percent of that in Basket Ball classes?

a) 101.45%

b) 104.76%

c) 113.84%

Downstream speed= 15/(3  ¾) = 4 km/hr

Upstream speed = 5/(2 ½) = 2 km/hr

Speed of River= ½(4-2) = 1 km/hr

In right angle isosceles triangle, angle will be 45º, 45º and 90º.

sinA + sinB + sinC = sin45º + sin45º + sin90º

= 1/√2 + 1/√2 + 1

= 1+√2

Average of 50 numbers = 42

Sum of 50 numbers = 50×42 = 2100

Sum of remaining numbers = 2100 – 64 – 46 = 2000

Average of remaining numbers = 2000/48 = 41.67

Area of triangle = ½ × Base × Height

Area of triangle CEF =1/2 × BC × EF

=1/2 ×BC× AB/3

= AB×BC/6

The area of ABCD = AB × BC

Required ratio =AB×BC/6: AB × BC=1:6

Ratio of profit = 3 : 2

So, ratio of investment = 3 :2

Total investment of A= 1500 × 12

So, total investment of B= 1500 × 12 ×2/3×1/ 2000 = 6

So, B joined after = 12 – 6 = 6 months Required percentage = 22/21 × 100 = 104.76%

Student enrolled in Swimming class = 11/100 × 3600 = 396

Student enrolled in Running class = 46.8/360× 3600 = 468

Total number of students enrolled = 396 + 468 = 864
