B.Mr Hari spends 66% of his salary on his family, 20% of the remaining he gives to a trust for charity and is leftwith12240. What is the total salary of Mr Hari and how much amount does he give to the trust?

Answer»

Let Salary = SSpent on family = 0.66 ×SRemaining = S - 0.66 S = 0.34 ×Sgiven to the trust = 0.20 ×0.34 ×S = 0.068 × S

What is left = 0.80 ×(0.34 ×S) = 0.272 S

0.272× S = 12, 240 Rs S = Rs 45, 000

given to trust = 0.068 ×S = Rs 3, 060

Or, Find the sum of all two-digit odd posive lhul17. In the adjoining figure, PA and PB aretangents drawn from an external point P to acircle with centre OProve that ZAPB- 2ZOAB

Answer»

given : a circle with centre O.

PA and PB are two tangents to the circle at A and B

To prove : L APB = 2 <OAB

Proof : join AB and OA

OA is perpendicular to PA (tangent and the radius at the point of contact)

therefore <OAP = 90degree

let <OAB = x

therefore <PAB = 90 - x ----- (1)

PA = PB (tangent from same external point)

therefore triangle APB is isosceles

therefore <PAB = < PBA = 90-x (angles opp to equal sides)

Tn triangle APB

<P + 90 - x + 90 - x = 180 degree (angle sum property)

<P + 180 - 2x = 180degree

<P = 2x

< APB = 2x

ie, < APB = 2 < OAB
