How we can solve this question by sir's method? A takes twice as much time as B and thrice as much time as C to finish a work . working together they can finish the work in 2 days. find the time which each will take to finish the work?
Well people who r asking to me tell us which exam have u cleared, so I would like to tell you all that frst exam which I cleared was UPP Computer Operator, 2nd was KVS LDC and the 3rd was Ibps pre. I don't know in India y we need to explain everything. Nd I didn't comment here for show off. I just shared it because dear sir is doing really a good job and with the help of online classes by other channels e.g WiFi study etc without Coaching a girl or a boy will be able to clear many exams.

But my trick works for this type questions. But I have a good trick for questions based on linear equations in two variables. Let's assume that the question is : The twice the son's age in years is added to the father's age, the sum is 70. But if twice the father's age is added to the son's age , the sum is 95 years. Find their ages : My friends, There is no need to form a quadratic equation. Here is a short trick. Let the son's age be x and Father's age be y. 2x + y = 70 x + 2y = 95 Now, Cross multiply 95 × y and 70 × 2y, Take y as 1 itself (70×2)( put minus symbol) ( 95×1) 140 - 95 ÷ same on reverse side that is , 2x × 2y - x × y 4 - 1 3 Now, x =( 140 - 95 )÷ 3 = 45÷ 3 . = 15 Therefore, son's age = 15 yrs father's age = find and say Hope it helps , bye Will be soon before you with a new trick

Sir ke pehle question ki meri short trick. Bohot easy :
A × B ÷ A + B
10×15 ÷ 10+15
150 ÷ 25
6
Wow that's good
Any similar trick applicable for other questions?
@@bishnuprasadswain4111 I will research
But my trick works for this type questions. But I have a good trick for questions based on linear equations in two variables.
Let's assume that the question is :
The twice the son's age in years is added to the father's age, the sum is 70. But if twice the father's age is added to the son's age , the sum is 95 years. Find their ages :
My friends,
There is no need to form a quadratic equation. Here is a short trick.
Let the son's age be x and Father's age be y.
2x + y = 70
x + 2y = 95
Now,
Cross multiply 95 × y and 70 × 2y,
Take y as 1 itself
(70×2)( put minus symbol) ( 95×1)
140 - 95 ÷ same on reverse side that is ,
2x × 2y - x × y
4 - 1
3
Now, x =( 140 - 95 )÷ 3
= 45÷ 3
. = 15
Therefore, son's age = 15 yrs
father's age = find and say
Hope it helps , bye
Will be soon before you with a new trick
