(a) Ahmad, a rickshaw puller does not have a regular income from rickshaw pulling; his earnings fluctuate every day. Sometimes, he earns enough to save some amount after buying his day to day necessities. On other days he is barely able to earn enough to survive.

(b) Ahmad has a yellow card which is a PDS card for below poverty line people. With this card Ahmad gets sufficient quantities of wheat, rice, sugar and kerosene oil for his daily use at rates below the market rates. In this way, Ahmad is able to survive even with less income from Rickshaw pulling.
