There are two Statements, Assertion and Reason (R).
Assertion : Larger the lead time, larger is the quantity of material required to be stored and larger shall be the amount of working capital required.
Reason (R): If the raw material does not have a record of uninterrupted availability, higher stock levels may be required. Choose the correct alternative from the alternatives given below:
To determine the correct relationship between the Assertion and the Reason (R) given in the question, we must analyze both statements:
Considering the analysis above, the correct answer is:
Both Assertion and Reason (R) are true and Reason (R) is the correct explanation of Assertion.

A ladder of fixed length \( h \) is to be placed along the wall such that it is free to move along the height of the wall.
Based upon the above information, answer the following questions:
(iii) (b) If the foot of the ladder, whose length is 5 m, is being pulled towards the wall such that the rate of decrease of distance \( y \) is \( 2 \, \text{m/s} \), then at what rate is the height on the wall \( x \) increasing when the foot of the ladder is 3 m away from the wall?
