Answer: Mean loan = 65.4 thousand rupees, i.e. ₹ 65,400

Class	Class mark \(x_i\)	Frequency \(f_i\)	\(f_ix_i\)
40–50	45	13	585
50–60	55	20	1100
60–70	65	24	1560
70–80	75	36	2700
80–90	85	7	595
Total		\(\sum f_i = 100\)	\(\sum f_ix_i = 6540\)

\[ \bar{X} = \frac{\sum f_ix_i}{\sum f_i} = \frac{6540}{100} \]

\[ \bar{X} \approx 65.4 \]
