Detailed Solution for SSC CPO Mock Test (Paper 1) - 5 - Question 120

Let angle be x

So, 1st angle is 1x

2nd angle is 2x

3rs angle is 3x

4th angle is 5x

& 5th angle is 9x

Sum of these angles is (1 + 2 + 3 + 5 + 9)x = 20x

Sum of the interior angle of a pentagon is = 540º

Hence x = 540 /20 = 27º

So, largest angle is 27 x 9 = 243º

By selling 12 marbles for a rupee, a shopkeeper loses 20%. In order to gain 20% in the transaction, he should sell the marbles at the rate of how many marbles for a rupee?

Detailed Solution for SSC CPO Mock Test (Paper 1) - 5 - Question 128

Given : S.P. of 12 marbles / 0.8 = Rs. 1.25

Now S.P. of 12 marbles at a gain of 20%

= C.P. x 1.2 = 1.25 x 1.2 = Rs. 1.5

It means in order to gain 20% he should sell 12 marbles for Rs. 1.5. Or for Re . 1 he should sell 12 /1.5 = 8 marbles.

SSC CPO Mock Test (Paper 1) - 5 - Question 133

Let PQ = 64 km A man starts from P and walks 32 km on first day, on second day he walks only 16 km, on third day he walks 8 km, on fourth day he walks just half, i.e. 4 km. He will reach Q in

Detailed Solution for SSC CPO Mock Test (Paper 1) - 5 - Question 133

Distance between PQ = 64 km

Distance covered on the 1st day = 64 2 = 32 km

Distance covered on the 2nd day = 32 2 = 16 km

Like wise Total distance covered = 32 + 16 + 8 + 4 + ..........

This is an infinite geometric series whose first term is 32 and common ratio = 1 2

∴ Sum of the infinite series = a 1 - r

Where a is the first term and r common ratio = 32 1 - 1 2 = 64

Hence the man will never reach Q

A can do a certain work in the same time in which B and C together can do it. If A and B together could do it in 10 days and C alone in 50 days, then B alone could do it in :

Detailed Solution for SSC CPO Mock Test (Paper 1) - 5 - Question 139

A = B + C

⇒ A + B + C = 6 units

But A = B + C

⇒ 2(B + C) = 6 units

⇒ B + C = 3 units

⇒ B + C - C = 3 - 1 = 2 units

⇒ B = 2 units

Hence, B alone did it in:

50 2 = 25 days
