if one of the statements alone is sufficient but other cannot sufficient

if either of the statements alone is sufficient

if both of the statements together are required, but not sufficient either of the statements alone.

if the statements not sufficient even by using both together.

- Statement I: 6 mobiles and 6 calculators cost Rs. 21000.

- This does not give us a direct price for the watch.

- Only provides information about mobiles and calculators.

- Statement II: A Calculator costs half as much as a watch.

- Gives a relationship between the cost of calculators and watches.

- Alone doesn’t give direct information about the cost of watches.

- Combining both statements:

- Both statements provide equations with different variables: mobiles, watches, and calculators.

- Still not enough to find the exact price of the watch since there are more variables than equations.

Correct Answer: Option 4

- Even using both statements, we cannot determine the exact cost of a watch.
