Question 1 of 10
1. Question

Question 2 of 10
2. Question
AC is a tangent to the given circle and AB is the radius. If AB = 9 cm, AC = 40 cm, then what is the length of DC?
Correct
Since BAC is right angled at A (radius is perpendicular to the tangent at the point of contact). So,
AC^{2} + AB^{2} = BC^{2}
AC^{2} + AB^{2} = (BD + DC)^{2}
40^{2} + 9^{2} = (9 + DC)^{2}
On solving we get, DC = 32 cm
Hence, option a.

7. Question
Refer the below data table and answer the following question.
The following table provides information about the number of hotels in Assam and Gujarat during the period 2005 to 2007.
2005 2006 2007 Assam 200 440 360 Gujarat 400 120 280 What was the ratio of the total number of hotels in Assam during the 3 years combined and the total number of hotels in Gujarat during the 3 years combined?
Correct
Required ratio = (200 + 440 + 360): (400 + 120 + 280) = 1000: 800 = 5: 4
Hence, option b.
Incorrect
Required ratio = (200 + 440 + 360): (400 + 120 + 280) = 1000: 800 = 5: 4
Hence, option b.

Refer the below data table and answer the following question.
The following bar graph provides information about the percentage of the total cost of different products that was transportation cost.
If the total cost for products A, B, C and D was Rs. 800, Rs. 500, Rs. 600 and Rs. 200 respectively, then what was the sum of the transportation cost for the 4 products combined?
Correct
Sum of the transportation cost for the 4 products combined = 0.2 Ć 800 + 0.1 Ć 500 + 0.25 Ć 600 + 0.05 Ć 200
= 160 + 50 + 150 + 10 = Rs. 370
Hence, option c.
Incorrect
Sum of the transportation cost for the 4 products combined = 0.2 Ć 800 + 0.1 Ć 500 + 0.25 Ć 600 + 0.05 Ć 200
= 160 + 50 + 150 + 10 = Rs. 370
Hence, option c.
