Ques:- X, Y and Z can do a piece of work in 24, 30 and 40 days respectively. They start the work together but Z leaves 4 days before the completion of the work. In how many days is the work done?
Recent Answer : Added by Admin On 2022-09-29 17:23:19:
One day’s work of A, B and C = (1/24 + 1/30 + 1/40) = 1/10.
C leaves 4 days before completion of the work, which means only A and B work during the last 4 days.
Work done by A and B together in the last 4 days = 4 (1/24 + 1/30) = 3/10.
Remaining Work = 7/10, which was done by A,B and C in the initial number of days.
Number of days required for this initial work = 7 days.
Thus, the total numbers of days required = 4 + 7 = 11 days.

Ques:- In a triangle two angles are in a ratio of 5:3 and the difference of the angles is 30 degrees. Find out the largest angle in the triangle
Recent Answer : Added by S pushpa On 2021-06-17 10:44:18:
Let A=5x,B=3x,C not given so consider C=x
In triangle total angle=180°
A+B+C=180°
5x+3x+x=180°
9x=180°
X=180°/9
X=20°
A=5(20)=100°
B=3(20)=60°
C=20°
Therefore A=100° is the largest angle
Ans: 100°
