can anyone help me to solve this problem ?

A small corporation has 7 shares of stock, and each share entitles its owner to one vote at a

stockholders meeting. The 7 shares are owned by 3 people as follows:

Mr.W:1 share

Mr.X:3 shares

Mr.Y:3 shares

Each of these persons has a switch to close (logic-1) when voting “YES” and open (logic-0) when

voting “NO” for his or her share(s).

Design a combination circuit that displays the total number of shares that vote “YES” for each

measure. Use a 7-segment display and a BCD-to-7-Segment decoder to display the number “YES”

votes. Use three 8x1 multiplexers (IC 74151) to design the combinational circuit that converts the input

from the stock owners' switches into the BCD input code for the 7447.
