B. 1650
C. 2000
D. 2350
E. 3650
F. 4000
G. Other(Specify Amount)
Simple yet confusing n challenging.

D : 2350

Step-by-step explanation:

Given,

The grocery price: 350

The amount lady gave: 2000

The amount returned to the lady: 1650

Also, given that the shopkeeper of the next shop comes with the Rs.2000 note saying "duplicate" *and takes his money back.

Therefore, the loss would be the sum of two items:

1) The shopkeeper have to return the 2000 rupees to the next shopkeeper. Therefore, he suffers the loss of 2000.

2) He also sold the grocery worth 350 rupees. Therefore, it would be the extra loss of 350 rupees.

Hence, the shopkeeper faced the loss of 2000 + 350 = 2350 rupees.

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
