Correct Answer: Rs. 3,450
Solution : Average saving of 10 students = Rs. 600 Total savings of 10 students = 10 × 600 = 6,000 Three students have no savings. Nihar's savings = Rs. 1,300 Rest of the 6 student's minimum savings = 6 × 250 = 1,500 $\therefore$ Remaining savings = 6000 – 1300 – 1500 = 3,200 Largest savings = remaining savings + individual savings = 3200 + 250 = 3,450 Hence, the correct answer is Rs. 3,450.
