A dishonest dealer professes to sell goods at the cost price but uses a false weight and gains 25%. Find his false weight age?

A dishonest dealer professes to sell goods at the cost price but uses a false weight and gains 25%. Find his false weight age?

A. 700 gms
B. 750 gms
C. 800 gms
D. 850 gms
Explanation:
25 = E/(1000 – E) * 100
1000 – E = 4E
1000 = 5E => E = 200
1000 – 200 = 800

A and B can do a work in 8 days, 13, and C can do the same work in 12 days. A, B and C together can finish it in 6 days. A and C together will do it in_________?

A and B can do a work in 8 days, 13, and C can do the same work in 12 days. A, B and C together can finish it in 6 days. A and C together will do it in_________?

A. 4 days
B. 6 days
C. 8 days
D. 12 days
(A + B + C)’s 1 day’s work = 1/6; (A + B)’s 1 day’s work = 1/8 (B + C)’s 1 day’s work = 1/12 (A + C)’s 1 day’s work = ( 2 X 1/6 ) – ( 1/8 + 1/12 ) = ( 1/3 – 5/24 ) = 3/24 = 1/8 So, A and C together will do the woirk in 8 days.

If x % of 80 = 20% of y, then x = ? and y = ?

If x % of 80 = 20% of y, then x = ? and y = ?

A. x = 20, y = 20
B. x = 20, y = 40
C. x = 20, y = 80
D. Cannot be determined
Explanation:
x % of 80 = 20 % of y => x / 100 (80) = 20 / 100 (y)
=> 4x = y
i.e x / y = ¼

The length of a rectangle is two – fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units?

The length of a rectangle is two – fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units?

A. 140
B. 156
C. 175
D. 214
Given that the area of the square = 1225 sq.units
=> Side of square = √1225 = 35 units
The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units
Given that breadth = 10 units
Area of the rectangle = lb = 14 * 10 = 140 sq.units
