Some equations are solved on the basis of certain system. Find out the correct answer for the unsolved equation on that basis
2 x 3 x 7 = 4949, 5 x 9 x 4 = 258116, 4 z 6 x 8 = ?
2 x 3 x 7
= (2)2 x (3)2 x (7)2
= 4949
5 x 9 x 4
= (5)2 x (9)2 x (4)2
= 258116
So, 4 x 6 x 8
= (4)2 x (6)2 x (8)2
= 163664

If 4x + 3y = 18xy and 2x - 5y + 4xy = 0 then the values of x and y will be respectively
4x + 3y = 18xy .....(1)
2x - 5y + 4xy = 0 .....(2)
Multiplying 2 in equation (2) we get
2 (2x - 5y + 4xy) = 0
⇒ 4x - 10y + 8xy = 0
⇒ 4x - 10y = - 8xy .....(3)
Subtracting equation (3) from equation (1) we get
13y = 26xy
⇒ x = 1 2
Putting the value of x in equation (1) we get
4 ( 1 2 ) + 3y = 18 ( 1 2 ) y
⇒ 2 + 3y = 9y
⇒ 2 = 6y
⇒ y = 1 3
The area of the sector of the circle is 1/10th the area of the circle. The angle of the sector is
Area of circle = A = πr2
Area of sectors of circle A = n 360 πr2
Where n = angle of the sector
According to question
n 360 πr2 = πr2 x 1 10
⇒ n 360 = 1 10
⇒ 10n = 360
⇒ n = 360 10 = 36

The average salary of male employees in a firm was Rs 5200 and that of females was Rs 4200. The mean salary of all the employees was Rs 5000,Percentage of female employees is
Let total number of employees = 100
Let total number of female employees = x
∴ Male employees = 100 - x
so 5200 (100 - x) + 4200x 100 = 5000
or 520000 - 5200x + 4200x = 50,0000
or 20000 = 1000x
∴ x = 20
Hence, percentage of female employees = 20 100 x 100 = 20%
