Due to increase in salary ofAjit Singh by 12 % new25760. Find his previous salary2

Answer»

Let previous salary be x

So, according to question

x + 12% of x = 25760

x + 12x/100 = 25760

x + 3x/25 = 25760

28x/25 = 25760

x = (25760 × 25)/28

x = 23000

So, previous salary is 23000

4. x & लिंए हल करें:-. 1 Lsin (sm cos lx) =1O Al s

Answer»

sin(sin⁻¹1/5+cos⁻¹x)=1

sin⁻¹1/5+cos⁻¹x=sin⁻¹1

But sinπ/2=1 ⇒sin⁻¹1=π/2So,

sin⁻¹1/5+cos⁻¹x=π/2--------Equation 1

In inverse trigonometry

sin⁻¹t+cos⁻¹t=π/2

So, equation 1 follows the above identity

So, sin⁻¹ 1/5+cos⁻¹x=π/2

Therefore value of x will be 1/5.

Answer»

We know,3 Median = Mode + 2 Mean

Thus,Median = 1/3(135.76 + 2*137. 05)= 1/3(135.76 + 274.1)= 1/3(409.86)= 136.62

Therefore,Median = 136.62
