Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3450.
Sum of amount savings of ten students = 600 × 10 = Rs 6000
Three students saving = 0
Remaining seven have savings = Rs 6000
Nihar has savings = Rs 1300
Remaining six have savings = 6000 - 1300 = Rs 4700
Out of six, Let 5 have at least Rs 250 saving and 6th has a x maximum saving
Now, 5 × 250 + x = 4700
x = 3450
