Either only I and II or only I and III is sufficient.
Neither I nor II is sufficient.
All I, II and III are sufficient.
Option C From I, invested by A = 48000 from I and II, Let, total investment of A and B = 100x investment of A = 60x investment of B = 40x ratio of investment A and B = 3 : 2 investment of B = 48000/3 * 2 = 32000 From I and III, Investment of A = 48000 Investment ratio of A and B = 3 : 2 investment of B = 48000/3 * 2 = 32000 either only statement I and II or only statement I and III is sufficient.
What is the present age of B ? I. The age of B is 4 years older than A. II. The ratio of present age of A and C is 5 : 4.
Only I is sufficient.
Only II is sufficient.
Either I or II is sufficient.
Neither I nor II is sufficient.
Both I and II are sufficient.
Option D From I, We can not get answer, from I and II, Let present age of A and C = 5x and 4x respectively. the age of B = 5x + 4 from I and II together we can not get answer.
