if statement II alone is sufficient but statement I alone is not sufficient.

**C**

if both statements I and II together are sufficient but neither of statements alone is sufficient.

**Soln.**

**Ans: c**

If we suppose the income to be Rs 100, then from statement I, A spends Rs 90 and saves Rs 10. From statement II, his expenses now become 99. Therefore, savings as becomes 120 − 99 = Rs 21. Hence, A's saving is increased by Rs 11 i.e., 110%.
