$\huge{\bf{\underline{\purple{\mathrm{\underline{\red{ANS}{\blue{WER}}}}}}}}$

Option " b "

Reason :

Actually the time taken by the sun rays to fall on one latitude is 4 minutes.

Actually the time taken by the sun rays to fall on one latitude is 4 minutes.so ,

The Time taken taken by the sun rays to fall on 75 ° East longitude is.

75 x 4 minutes

= 300 minutes.

Now convert this minutes into hours

for this conversion just divide it by 60

so, 300/60 = 5 hours. ( time gap)

So , If the time is 12 noon at 0 ° longitude then

The time at 75 ° east longitude is

(after 12 pm after start counting till 5 numbers )

so we get the time at 75° east longitude as 5 : 00 P.M.
