If x% of $25/2$ is 150, then the value of x is :

a) 1400

b) 1500

c) 1000

d) 1200

Answer: (d)

Question : 22 [SSC CGL Prelim 2005]

If 20% of (P + Q) = 50% of (P –Q), then find P : Q

a) 7 : 5

b) 5 : 7

c) 7 : 8

d) 7 : 3

Answer: (d)

${20(P + Q)}/100 = 50/100(P – Q)$

${P + Q}/{P - Q} = 5/2$

${2P}/{2Q} = {5 + 2}/{5 - 2}$

[By componendo & dividendo]

$P/Q = 7/3$ or 7 : 3

Question : 23

The time duration of 1 hour 45 minutes is what percent of a day?

a) 8.3 %

b) 8.24 %

c) 7.218 %

d) 7.292 %

Answer: (d)

1 hour 45 minutes = 1$3/4 hours = 7/4$ hours

1 day = 24 hours

Required per cent = ${7/4}/24 ×100$

= $7/{4 × 24}$× 100

= 7.292%

Question : 24

a) 60

b) 15

c) 3600

d) 600

Answer: (a)

p% of p = 36

$p/100$× p = 36

$p^2$ = 3600

p = 60

Question : 25

If 40% of (A + B) = 60% of (A – B) then $\text"2A - 3B"/ \text"A + B"$ is

a) $5/6$

b) $6/5$

c) $7/6$

d) $6/7$

Answer: (c)

$(A + B) × 40/100 = (A – B) × 60/100$

2 (A + B) = 3 (A – B)

2A + 2B = 3A – 3B ⇒ A = 5B

${2A - 3B}/{A + B} = {10B - 3B}/{5B + B}$

= ${7B}/{6B} = 7/6$
