220
320
330
400
120
Option B

7. Sunetra invested an amount of Rs. 50,000 to start a software business. After six months Nikhil joined her with an amount of Rs 80,000. At the end of 3 years they earned a profit of Rs. 24,500. What is Sunetra’s share in in the profit ?
Rs. 17,550
Rs. 20,000

10%
50%
70%
40%
20%
Option A
𝐷𝑖𝑓𝑓𝑒𝑟𝑒𝑛𝑐𝑒 = 𝑝𝑟 ^2/ 100^2
=>180 = 18000𝑟^ 2/100 × 100
=>180 × 100 × 100 = 1800𝑟^2
=> r=10%

10 m
21 m
40 m
Option D
𝐼𝑛𝑛𝑒𝑟 𝐶𝑖𝑟𝑐𝑢𝑚𝑓𝑒𝑟𝑒𝑛𝑐𝑒 𝑜𝑓 𝑡h𝑒 𝑡𝑟𝑎𝑐𝑘 = 396𝑚
=>2𝜋𝑟 = 396
=> 𝑟 = (396 × 7)/( 22 × 2) = 63𝑚
𝑂𝑢𝑡𝑒𝑟 𝐶𝑖𝑟𝑐𝑢𝑚𝑓𝑒𝑟𝑒𝑛𝑐𝑒 𝑜𝑓 𝑡h𝑒 𝑡𝑟𝑎𝑐𝑘 = 528𝑚
=> 2𝜋𝑅 = 528 𝑅
= (528 × 7)/( 2 × 22)= 84𝑚
𝑊𝑖𝑑𝑡h 𝑜𝑓 𝑡h𝑒 𝑡𝑟𝑎𝑐𝑘 = 84 − 63 = 21 m

5/9
3/7
1/8
1/24
7/13
Option C
Total number of fruits=4+5+9=18
𝑃𝑟𝑜𝑏𝑎𝑏𝑖𝑙𝑖𝑡𝑦 𝑡h𝑎𝑡 𝑂𝑟𝑎𝑛𝑔𝑒 𝑖𝑠 𝑑𝑟𝑎𝑤𝑛 𝑖𝑛 𝑜𝑛𝑒 𝑑𝑟𝑎𝑤 = 9 /(4 + 5 + 9) = 1/2
Required probability of drawing 3 fruits with replacement such that all the fruits are oranges
= 1/ 2 × 1/ 2 × 1/ 2 =1/8
