Let \(E=\) event of getting a multiple of 3 or \(5=\{3,6,9,12,15,18,5,10,20\}\)

\(\therefore P(E)=\frac{n(E)}{n(S)}=\frac{9}{20}\)

Hence option D is the correct answer.

Question 7

A grocer has a sale of Rs. 6435, Rs. 6927, Rs. 6855, Rs. 7230 and Rs. 6562 for 5 consecutive months. How much sale must he have in the sixth month so that he gets an average sale of Rs. 6500?

A
Rs. 4991

B
Rs. 5991

C
Rs. 6001

D
Rs. 6991

Solution

Total sale for 5 months = Rs. (6435 + 6927 + 6855 + 7230 + 6562) = Rs. 34009.
∴ Required sale = Rs. [ (6500 x 6) - 34009 ]
= Rs. (39000 - 34009)
= Rs. 4991.
Hence option A is the correct answer.
