Study the following graph and answer the question below.
Total investment(in ₹ thousands) of Vivek and Shalini in six savings schemes.
Percentage of Vivek's investment out of total investment
What is the average amount invested by Vivek in savings schemes A, B , C and D?
Answer & explanation
Correct answer: option 3
Total investment in A = 80000
Total investment in B = 70000
Total investment in C = 30000
Total investment in D = 50000
Investment of vivek in A = \(\frac{50 }{100 }\) × 80000 = 40000
Investment of vivek in B = \(\frac{60 }{100 }\) × 70000 = 42000
Investment of vivek in C = \(\frac{40 }{100 }\) × 30000 = 12000
Investment of vivek in D = \(\frac{30 }{100 }\) × 50000 = 15000
Average investment by vivek in A , B , C & D = \(\frac{40000+42000+12000+15000 }{4 }\)
= \(\frac{ 109000 }{4 }\)
= Rs. 27250
