Is this solution Helpfull? Yes (8) | No (1)  

Debraj Das  (2 Months ago)

Let no.s are 13a and 13b.

so,
13a x 13b = 2028
or,
ab = 12.

Now, the co-primes with product 12 are (1, 12) and (3, 4).

[Note: Two integers a and b are said to be coprime or relatively prime if they have no common positive factor other than 1 or, equivalently, if their greatest common divisor is 1 ]

So, the required numbers are (13 x 1, 13 x 12) and (13 x 3, 13 x 4).

Ans: there are 2 such pairs.

at 4.20 hr hand is slightly greater than 4'o clock so ans is 10 deg

mnt hand moves 120deg in 20 mnts
and hr hand at exact 4 is 120 bt in 4+1/3 hr it is 10 greater than mnt

Is this solution Helpfull? Yes | No   

Mani kandan  (2 Months ago)

ans is b)10 degree
It is 4 degree.
Because hour hand moves 30 degree in 1hour.
4:20 = 4 +20/60 = 4+1/3 = 13/3.
So it is 1/3 hours passed so it rotates 10 degree.
Total angle of hours hand is 30*4+10 = 130 degree.

Minute hand moves 6 degree in 1 minute = 20*6 = 120 degree.
So 130-120 = 10 degree.
