If X^Y denotes X raised to the power of Y, find out last two digits of
(2957^3661) + (3081^3643)

Reply Like? Yes | No

Anand Dwivedi 10 years ago

(2957)^3661
(2957)^3660 * (2957)^1=2957,
so last two digits be 57.
2nd (3081)^3643=(3081)^3640 * (3081)^3=>for last two digits it will be
(81)^1 * (81)^2=81*6561=531441=>so last two digit is 41 than add
sum 57+41=98 will be answer

Required sum = (80 - 3 x 3) years
(80 - 9) years = 71 years. will be Answer

Satya Karteek 10 years ago

Ans is 71..
Because, the sum of their present ages is 80.
If we need to calculate for 3 years back, we have to reduce 3 from each person, so 3*3=9, and 80-9=71 is the answer..

Reply Like? Yes (28) | No (6)

Devendra Marghade 10 years ago

64 minutes

If distance=x, then x/100= 80/60=4/3 , x=400/3 Km.
with the speed of 125 kmph, distance x will be covered in (400/3)/125= 16/15 hours

so 3 digit no having atleast one 6 =Total no of 3digits no-Total no of 3digits no in which 6 is not appear
total combination of 3 digit=I II III
9 x 10 x 10=900(since hundrad place can file only by 1,2.....9 not include 0 if include zero then it becomes 2 digit no hence hundrad place can fill only 9 ways)
no not having digit 6 are (0,1,2,3,4,5,7,8,9) only 9 posibility to file a place accept hundrad place =8x9x9=648

3 digit no having at least one 6=900-648

If speed of the trains= x & y m/s respectively, then
