Q) what’s the acute angle between the minute hand and the hour hand of a clock at 3:26?

1) 51* 2) 53* 3) 59* 4) 60*

: * mean degree

option b) must be correct

Initially the hour hand is 90* wrt the minute hand. The movement for hour hand per/min is 1/2* and for minute hand is 6*.

for 26' , minute hand moves 156*
for 26' , hour hand moves 13*. total = 90+13 =103*

acute angle = 156 -103 =53*

at 3 pm angle btwn hour and min hand = 90

in 26 min min hand move 26*6 = 156 degree
hour hand move 26*0.5 = 13 degree
hence angle at 3:26PM = 156 - (90+13) = 53

Dear All, I'm sharing the last QQAD Practice test that was delivered in October 07. This has both problems as well as solutions except for question 3 where the figure went missing. Hope this helps in your early preprations.

243 has been divided into three parts such that half of the first part,one third of the second part and one fourth of the third part are equal.The largest part is

a)74
b)86
c)92
d)108

108..

work with the option starting with 92, as the largest no is divisible by 4

hi bro
ques is correct and complete......answer is 53 degrees
there's direct formula 2 find angle betw hands of the clock

if
H=hours
M=minutes

then
ANGLE=30H-(11/2)M

key concepts related 2 these kind of probs r:-
>>a minute hand gains 11/2 degrees over hour hand every minute
>>after 12,the minute and hour hand coincide after interval of 720/11 mins
>>the hour and minute hand will interchange the position after n*(600/11)mins.

hope this will help....

rock on..

26*6-(3*30+26*0.5)=53

let the equal portion be x
then 2x+3x+4x=243
9x=243
x=27
so largest =108
