Rationalise the donemena hue

Answer»

3 + sqrt(2)/ 4 sqrt(2)

To rationalise Multiply and Divide by 4 sqrt(2)

We get,(3+ sqrt(2))*4sqrt(2)/4sqrt(2)*4sqrt(2)

= (12 sqrt(2) + 8)/ 4*2

= 4(3sqrt(2) + 2)/8

= (3 sqrt(2) + 2)/2

When the son will be as old asfather today, the sum of their ageswill be 126. when the father wasold as his son today, the sum of thisages then was 38. Find their presentage. [Ans. 52 yrs. and 30 yrs.]

Answer»

Let the present age of son = x

and the present age of father = y

Difference in their ages = y - x

Given, when the ages will be as old as father today their ages will add up to 126 years

=> {x + (y - x)} + {y + (y - x)} = 126

=> {x + y - x} + {y + y - x} = 126

=> y + 2y - x = 126

=> 3y - x = 126 .................1

Again, when the father as old as son is today, their ages add up to 38 years

=> {y + (x - y)} + {x + (x - y)} = 38

=> {y + x - y} + {x + x - y} = 38

=> x + 2x - y = 38

=> 3x - y = 38 .................2

Multiply by 3 in equation 2, we get

=> 9x - 3y = 114 ..............3

Add equation 1 and 3, we get

8x = 240

=> x = 240/8

=> x = 30

From equation 1, we get

3y - 30 = 126

=>3y = 126 + 30

=> 3y = 156

=> y = 156/3

=> y = 52

So, the present age of son = x = 30 years

and the present age of father = y = 52 years

16. One borrowed Rs.1600 at Rate 15% and paidRs. 1800 after 18 months. The amount he stillowes is...1. Rs. 2003. Rs. 1602. Rs. 2504. Rs. 170

Answer»

SI = P*R*T/100Given P = 1600, R = 15%, T = 18/12 = 3/2

SI = 1600*15*3/200 = 48*15/2 = 360

Amount due after 18 months = 1600 + 360 = 1960

Amount already paid = 1800

Amount he still owes = 1960 - 1800 = Rs 160

Answer»

We know,SI = P*R*T/100

To calculate monthly income for given scenarioP = 4000, R = 14 - 10 = 4%,T = 1/12

SI = (4000*4*1)/(12*100) = 160/12 = 13.35

MJUQ406513. In Fig., a square OABC is inscribedin a quadrant OPBQ. If OA = 20 cm,find the area of the shaded region.(Use A = 3.14)Sol. Side of a square OABC = 20 cmArea of a square OABC = (20)2- 100 cm2

Answer»

Area of square OABC=l²=20²=400cm²---(1)

To Find The Radius join OB

Now by applying Pythagoras in triangle OAB,We Get,

OA²+AB²=OB²

=400+400=OB²(as OABC Is a square And OA=AB=20)

Let OB²=r²

Area of quadrant =1/4*π*r²

=1/4*314/100*800

=628cm²-----(2)

Now Area Of Shaded Region =(2)-(1)

=628-400

=228cm²
