• B. 40
• C. 20
• D. 10

Answer 1

The correct option is C

20

Refer to the table given below:
$\begin{array}{cccc}\text{Asset}& & & \\ \text{Flats (Rs.in lakhs)}& 30+30=60& & 30\\ \text{House (Rs.in lakhs)}& & 50& \\ \text{Bank deposits (Rs.in lakhs)}& x_1& x_2& 70-(x_1+x_2)\\ \text{Coins (Total number=n and)}& \frac{n}{3}& \frac{n}{3}& \frac{n}{3}\\ \text{Total value=n}\times 1=\text{Rs.n lakhs)}& & & \\ \text{Total (Rs. in lakhs)}& 60+x_1+\frac{n}{3}& 50+x_2+\frac{n}{3}& 30+70-(x_1+x_2)+\frac{n}{3}\end{array}$
Given, the total value of the assets is distributed equally among the three children. Then
$60+x_1+\frac{n}{3}=50+x_2+\frac{n}{3}=30+70-(x_1+x_2)+\frac{n}{3}$
Taking $60+x_1+\frac{n}{3}=50+x_2+\frac{n}{3}$, we get
$x_2-x_1=60-50=10-----------\left(1\right)$
Now taking $50+x_2+\frac{n}{3}=30+70-(x_1+x_2)+\frac{n}{3}$, we get
$x_1+2x_2=50---------\left(2\right)$
Putting the value of $x_2$ from (1) into (2), we get
$x_1+2(x_1+10)=503x_1=30$
$x_1=10$ lakhs
Hence, $x_2=20$ lakhs & $(70-x_1-x_2)=70–10–20=40$ lakhs
Since, it is given that Neeta received the least amount in bank deposits, therefore Neeta received $x_1$ = Rs. 10 lakhs in bank deposits, as Geeta received the highest deposits. So, Geeta received Rs. 40 lakhs and Seeta received $x_2=20$ lakhs in bank deposits.
Hence, the updated table is as follows:
$\begin{array}{cccc}\text{Asset}& \text{Neeta}& \text{Seeta}& \text{Geeta}\\ \text{Flats (Rs.in lakhs)}& 30+30=60& & 30\\ \text{House (Rs.in lakhs)}& & 50& \\ \text{Bank deposits(Rs. in lakhs)}& 10& 20& 40\\ \text{Coins (Total number=n and)}& \frac{n}{3}& \frac{n}{3}& \frac{n}{3}\\ \text{Total value=n}\times \text{1=Rs.n lakhs)}& & & \\ \text{Total (Rs. in lakhs)}& 70+\frac{n}{3}& 70+\frac{n}{3}& 70+\frac{n}{3}\end{array}$
Seeta received Rs. 20 lakhs in bank deposits.
