How did you get the 4th answer?

[bhavya jain]

for 4th. If we have 325 Rs, then total amount in 3yrs equal 975 Rs.
Now say P=325 & we are given R=12%. So SI=325*12*3/100=117. Thus 117+975=1092RS.
I hope u got it..

[abhinav619]

Oh yes! I was not getting it the other way. Thanks

[bhavya jain]

@ Depasana which question are u talking about?

[deepasna.kalra]

QUES 1 of sections a. What percentage of nos from 1 to 70 have squares that end in digit 1?

[Economics student]

In economics, an externality is the benefit that affects a party who did not choose to incur that benefit.
By this logic shouldn't the ans for 7th one be (d)? Because for the option (b), it is construction of road FOR facilitating the transport. So its done with the motive of facilitating transport right?
Or am I just over-thinking?
