Answers
Answer:
As per the given statement,
Ravi starts from A and moves along the route A-B-E-C-D
D is the finishing point and to calculate AD:
we have BE = EC = (6/2) = 3 km
so using Pythagoras theorem, in the △ ABE:
AB

+BE

=AE

+3

=AE

AE=5 Km
Similarly, in △ ECD,
ED = 5 km
and AD = AE + ED = 5 + 5 = 10 km
option B
solution
answer is 10 km.
Q.6
ans
Mohan deposit amount = Rs 2000
He withdrawns next day = Rs 1642
therefore, the balance = 2000-1642\ =\ 3582000−1642 = 358
thus, the balance in Mohan's account after withdrawal = Rs 358
Answer:
Hari traveled 36 km to the west from point P and then 48 km to the east from that point.
To do :
We have to find how far from point P was Hari finally.
Solution :
If the original position of the Hari (point P) is considered as 0, east of the original position as positive and west of the original position as negative, then
The final position of Hari is, 0+(-36) km+(48)-(36) =+12
