A.
8%
Let principal = ₹ P
∴ S.I. = 3P - P = ₹ 2P
According to the question,
The distance between the points (0, 0) and the intersecting point of the graph of x = 3 and y = 4 is
3 units
2 units
5 units
4 units
C.
5 units
Coordinate of intersection point of x = 3 and y = 4 is (3, 4).
∴ Required distance:
A container has 80 L of milk. From this container, 8 L of milk was taken out and replaced by water. The process was further repeated twice. The volume of the milk in the container after that is
58.23 L
85.23 L
58.32 L
85.32 L
C.
58.32 L
Shortcut Method:
Volume of milk left after 3 operations:
The odd element in the sequence

A and B can separately do a piece of work in 20 and 15 days respectively. They worked together for 6 days after which B was replaced by C. The work as finished in next 4 days. The number of days in which C alone could do the work is
30 days
45 days
40 days
35 days
C.
40 days
Work done by A and B together in 6 days:
Remaining work:
Now, this remaining work done by A and C in 4 days
∴ The whole work will be completed by A and C in:
∴ Net work done by C in 1 day:
∴ The no of days in which c alone could do the work is 40 days.
