If the number of boys participating in the sports is 15, then how many girls are there in the class? (1) Data inadequate (2) 20 (3) 25 (4) 30 (5) None of these
Recent Answer : Added by Admin On 2020-05-17 12:03:57:

let no. of boys not participating be x
then the no. of girls not participating = x+5
no. of boys : girls participating = 3:2
given no.of boys participating = 15
therefore, the ratio is now 15:y(say)
then 3:2 = 15 : x
on solving 3/2 =15/y ie.., 3y =30 we get y =10
hence no. of girls participating =10
therefore total no of students paricipating = 15+10=25
total no of students in class =60 given
hence no. of students not participating = 60-25=35
therefore x+(x+5)=35
2x=30
x=15
therfore no of girls not participating =15+5=20
therefore total no of girls in class = no of girls
participating + no of girls not participating
=10+20
=30 is the answer

Recent Answer : Added by DK BOSS On 2021-07-17 06:27:50:

Maximum number of edges = 9. Start from one corner. Select any face including that corner. Complete a square (4 edges) around the face to reach at the starting corner point . Now, move to the opposite face through the edge joining them and passing through the starting point(1 edge). Now, complete the square of edges around this face(4 edges). Total = 4+1+4 = 9 edges

This is more logical …

Let the 1st flag 1 placed at the origin ….
in crossing 8 flags he traveled 7 distances….
s=d/t
=7/8

time for 4 flags t=(d/s)=4/(7/8)=(4*8)/7=4.5714285714285714285714285714286

Recent Answer : Added by Admin On 2022-09-29 16:36:42:

answer :
Let the distance which I walk to the station be x km Then Time needed to reach the station at 3 km/hr = (3x​+602​) hrs and
Time needed to reach the station at 4 km/hr = (4x​+602​) hrs But 3x​+301​=4x​−301​⇒3x​−4x​=−302​=151​
⇒124x−3x​=151​⇒12x​=151​⇒x=1512​=54​ km

Ques:- Find out the wrong number in the series:
15, 16, 34, 105, 424, 2124, 12576
A. 34
B. 105
C. 424
D. 2124
Recent Answer : Added by G S Dheeraj On 2022-08-14 16:33:59:

The series is 15, 16, 34, 105, 424, 2124, 12576
1) (15*1) + 1 = 16
2) (16*1) + 2 = 34
3) (34*3) + 3 = 105
4) (105*4) + 4 = 424
5) (424*5) + 5 = 2125
Clearly, they gave 2124 instead of 2125, so it is the wrong number in the series.

Ques:- Some of the friends decided to go on a picnic they decided to go on a bike if the biker decided to take one pillion with him then there is no means of travel for the people as equal to the no of bike + 1. if they decided to go on two trip three bike r left unused in the second trip find the no of person having bike?
Recent Answer : Added by Admin On 2020-05-17 12:03:16:

If there are n bikes then the no. of people are 2n+1. n are dropped in firs trip, in second trip 3 bikes are unused, so 2n-3 + n covers 2n+1 people. i.e. n + 2n – 3 = 2n +1
n = 4
No. of people = 9
