guys can somebody help me with am>=gm wala concept,its not coming right on a consistent basis for me
😠

How many subsets A of {1,2,3,4,5,6,7,8,9,10} have the property that no two elements of A sum to 11 ?
@rubikmath Puys.. plz help..!!


A,B & C can independently do work in 15 days,20 days,30 days respectively.They worked together for some days and after that c leaves.Amount paid to them is 18,000.B gets 6ooo more than c.For how many days does A worked?

In Triangle ABC, Angle A = 90. The diameter of the semi-circle lies on the side BC, and the semi-circle touches the sides AB and AC. The centre of the circle divides BC in the ratio of 3 : 4. Also, AB + AC = 28 cm. Find the approximate area of the triangle not covered by the semi circle.



Plz post the explanation too 😃
