One collective farm got an average harvest of 21 tons of wheat and another farm that had 12 acres of land less given to wheat, got 25 tons from a hectare. As a result, the second farm harvested 300 tons of wheat more than the first. How may tons of wheat did each farm harvest?
Remainder of 3^1001 divided by 1001?
@pratiksahoo33 Approach for this bhai ?? I reduced it till : 3^ 281/ 1001. Now since 1001= 11*13*7 (all prime factors) , we can find remainder from individual prime factors.. But what to do after it ? Confused :-|

Hi All,
Sorry for posting out of context.
I completed filling my CAT application form and proceeded to pay using my debit card. However, much to my surprise, the payment apparently failed, although Rs 1600 got deducted from my bank account.
I tried to validate the functionality of my debit card by making other online transactions, and all of them worked fine. I cannot seem to understand why I'm unable to submit the exam fee. Has anyone else faced any such payment issues?
DEV AND NISHIT STARTED SIMULTANEOUSLY FROM OPPOSITE POINTS X AND Y FROM A STRAIGHT ROAD,AT CONSTANT SPEEDS.WHEN DEV HAD COVERERD 40% OF THE DISTANCE FROM X TO Y,NISHIT WAS 4KM AWAY FROM DEV AFTER HAVING CROSSED DEV. WHEN NISHIT HAD COVERED HALF THE WAS 10KM SHORT OF HALF THE WAY. FIND THE POSSIBLE OF TIME IT TOOK DEV TO COVER THE DISTANCE FROM X TO Y TO THE TIME IT TOOK NISHIT TO COVER THE SAME DISTANCE
Options 1) (1+3^1/2)/2
2) (3*2^1/2+4)/(2^1/2+1)
3)BOTH
4)NONE OF THESE
A rectangle PRSU, is divided into two smaller rectangles PQTU, and QRST by the line TQ. PQ = 10 cm.
QR = 5 cm and RS = 10 cm. Points A, B, F are within rectangle PQTU, and points C, D, E are within the rectangle QRST. The closest pair of points among the pairs (A, C), (A, D), (A, E), (F, C), (F, D), (F, E), (B, C), (B, D), (B, E) are 10√3 cm apart. Which of the following statements is necessarily true?
- Distance between A and B is greater than that between F and C
- None of the above
- Both (a) and (b)
- The closest pair of points among the six given points is (C, D), (D, E), or (C, E)
- The closest pair of points among the six given points cannot be (F, C)
