Angela deposited 15000 rupees in a bank at a rate of 9 p.c.p.a. She got simple interestamounting to 5400 rupees. For how many years had she deposited the amount?​

Answer»

\begin{gathered}\sf Given \: that \begin{cases} & \sf{Simple \: interest \: = \bf{Rs \: 5400}} \\ & \sf{Rate \: of \: interest \: = \bf{9\:\% \: per \: annum}} \\ & \sf{Principal \: = \bf{Rs \: 15000}} \end{cases} \end{gathered}

\begin{gathered}\begin{gathered}\bf \: To\:find - \begin{cases} &\bf{Time \: in \: <klux>YEARS</klux>} \end{cases}\end{gathered}\end{gathered}

\begin{gathered}\Large{\bold{{\underline{Formula \: Used - }}}} \end{gathered}

Understanding the concept :-

Principal: The principal is the amount that initially BORROWED from the bank or INVESTED. The principal is denoted by P.

Rate: Rate is the rate of interest at which the principal amount is given to someone for a certain time. The rate of interest is denoted by R.

Time: Time is the duration for which the principal amount is given to someone. Time is denoted by T.

Amount: When a person takes a loan from a bank, he/she has to return the principal borrowed plus the interest amount, and this total returned is called Amount.

Amount = Principal + Simple Interest

{\bf{\ Simple \: interest \: = \: \dfrac{P \times R \times T}{100}}}

where,

  • P denotes Principal

  • R denotes Rate

  • T denotes Time

\large\underline{\bold{Solution-}}

Given that,

  • Principal, P = Rs 15, 000

  • Rate of interest, R = 9 % per annum

  • Simple Interest = Rs 5400

Let time period, for which Principal is invested is 't' years.

On substituting all the values in formula of Simple interest,

{\sf{Simple \: interest \: = \: \dfrac{P \times R \times T}{100}}}

\: \sf \: 5400 = \dfrac{150 \: \: \cancel{00} \times 9 \times t}{ \cancel{100}}

\bf \: t = \: \sf \: \dfrac{5400}{150 \times 9} = 4 \: years

So,

  • Required time is 4 years.

Two parallel chords of lengths 30 cm and 16 cm are drawn on opposite sides of the centre of a circleof radius 17 cm , find the distance between the chords .​

Answer»

Step-by-step explanation:

Consider AB and CD as the chords of CIRCLE with centre O It is GIVEN that AB = 30cm and CD = 16cm Join the lines OA and OC We know that AO = 17cm and CO = 17cm Construct OM ⊥ CD and OL ⊥ AB Perpendicular from the centre of a circle to a CHORD bisects the chord We know that AL = ½ × AB By substituting the values AL = ½ × 30 So we get AL = 15cm We know that CM = ½ × CD By substituting the values CM = ½ × 16 So we get CM = 8cm Consider △ ALO Using the Pythagoras theorem it can be written as AO2 = OL2 + AL2 By substituting the values 172 = OL2 + 152 So we get OL2 = 172 – 152 On further calculation OL2 = 289 – 225 By subtraction OL2 = 64 By taking the square root OL = √64 OL = 8cm Consider △ CMO Using the Pythagoras theorem it can be written as CO2 = CM2 + OM2 By substituting the values 172 = 82 + OM2 So we get OM2 = 172 – 82 On further calculation OM2 = 289 – 64 By subtraction OM2 = 225 By taking the square root OM = √225 OM = 15cm So the distance between the chords = OM + OL By substituting the values Distance between the chords = 8 + 15 = 23cm Therefore, the distance between the chords is 23 cm.Read more on Sarthaks.com - HTTPS://www.sarthaks.com/727461/two-parallel-chords-lengths-30cm-16cm-drawn-opposite-sides-the-centre-circle-radius-17cm
