Ek pensalaka watinakama = 60/7= 8.571
Pensal 1k wikunum mila = 70/4 = 17.5
Pensalakin laabaya = 17.5-8.571= 8.93

Labaya 1000 wimata wikiniya yuthu pensal ganana = 1000/8.93=112

Code:
එක පැන්සලකින් ලැබෙන ලාබය = 70 - 60 =10
අපේක්ෂිත ලාබය                       = 1000
දැනට ලබා ඇති ලාබය               = (70-60) * 4 = 40
ඉදිරියට ලැබිය යුතු ලාබය           = 1000 - 40 = 960
ඉදිරියට විකිණිය යුතු පැන්සල්  ගණන = 960 / 10 = 96
ඔය ප්‍රශ්නේ පැහැදිලි නෑ. වෙළෙන්දා ළඟ ඉතුරු පැන්සල් 3 යි නේ මචන්. එතකොට වෙළෙන්දාට කොච්චර ලාබයක් ගන්නත් විකුණන්න වෙන්නේ පැන්සල් 3 ම තමයි. ඔය හදල තියෙන්නේ, වෙළෙන්දා ආයිත් පැන්සල් අරන්, 70 ගානේ විකිනුවොත් එන විදිහ.

Quote:
Rs.60k bagin pensal 7k milata gani. Ohu newatha Rs.70 bagin pensal 4k wikunai.
මෙතන පැන්සල් 7ම රු. 60 ද, නැත්තම් එක පැන්සලක් රු 60 ද?

පැන්සලක් විකුනන්නේ 70/4 කට, ගන්නේ 60/7 කට. එක පැන්සලකින් ලාබෙ = 70/4 - 60/7

1000 ක් හොයන්න විකුනන්න ඕනේ පන්සල් ගාන = 1000/(70/4-60/7) = 112
