Answer: D It is given that, PQ*RQ = XXX There are 9 numbers of the form XXX 111 = 3*37, 222=6*37, 333=9*37, 444=12*37, 555=15*37, 666=18*37 777=21*37, 888=24*37, 999=27*37 Only in 999, we get the unit's digit of the two numbers the same. Since, there is a unique value, so we need neither statement I nor statement II to answer the question.
Q. No. 194:
In a trapezoid PQRS, PS is parallel to QR, PQ and SR are extended to meet at A. What is the value of ∠PAS ? I. PQ= 3, RS=4 and ∠QPS = 60°. II. PS=10, QR=5
A :
Statement I alone is sufficient to answer the question
B :
Statement II alone is sufficient to answer the question
C :
Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question
D :
Either statement I or Statement II alone is sufficient to answer the question
Answer: A PQ =3, RS =4 ∠QPS = 60° Draw a line segment QB parallel to RS Draw a perpendicular QC to PB. Now, ∠PQC = 30°, PC = 3/2 , QC = 3√3 /2 BC = (QB2 - QC2 )1/2 After knowing an angle and 3 sides of a triangle all the angles can be found. Statement II, Insufficient information.
Q. No. 195:
A sequence of positive integer is defined as An+1 = An2 +1 for each n≥0. What is the value of the Great Common Divisor of A900 and A1000 ? I. Ao =1. II.A1 =2
A :
Statement I alone is sufficient to answer the question
B :
Statement II alone is sufficient to answer the question
C :
Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question
D :
Either statement I or Statement II alone is sufficient to answer the question
Answer: D Statement I : Ao = 1, A1 =1, A2 =2 A1 = Ao2 +1 = 2. A2 = A12+1=5 Thus, we can calculate A900 and A1000 and answer the question. Statement II : A1 = 2, A2 = A12+1=5 and so on... Thus we can also find the answer from this statement alone.
Q. No. 196:
For each rupee in monthly advertising expenditure, KUMAR & Co. experiences a Rs6 increase in sales. How much KUMAR & Co. has to spend on advertising to attain Rs1000000 in sales revenue for the month ? I. Without advertising KUMAR & Co. earns Rs 200000 sales revenue per month. II. When company KUMAr & Co spend Rs15000 on advertising it earns Rs 290000 as sales revenue.
A :
Statement I alone is sufficient to answer the question
B :
Statement II alone is sufficient to answer the question
C :
Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question
D :
Either statement I or Statement II alone is sufficient to answer the question
Answer: D Statement I : Revenue due to add = Rs 800000 Rs 6 revenue comes from Re 1 expenditure to add Re 1 revenue from Re 1/6 expenditure on add. Rs 800000 revenue comes from Rs 800000/6 expenditure on add Hence I alone is sufficient. Statement II : Re 1 on add occurs Rs 6 Rs 15000 on add occurs Rs 90000 revenue without add = Rs 200000Now, Rs 800000 more revenue is to be mopped up Rs 6 for Re 1 on add Rs 800000 for 800000/6 on add. Statement II alone is sufficient.
Q. No. 197:
Geetanjali Express, which is 250m long when moving from Howrah to Tatanagar crosses Subarnarekha bridge in 30 sec. What is the speed of Geetanjali Express. I. Bombay Mail, which rums at 60kmph crosses Subarnarekha bridge in 30 sec. II. Bombay Mail when running at 90kmph crosses the lamp post in 10 sec.
A :
Statement I alone is sufficient to answer the question
B :
Statement II alone is sufficient to answer the question
C :
Statement I and Statement II together are sufficient, but neither of the two alone is sufficient to answer the question
D :
Either statement I or Statement II alone is sufficient to answer the question
Answer: C Statement I gives the sum of lengths of Bombay Mail and Subarnarekha bridge. Statement II gives the length of Bombay mail With the help of two statements we can get the length of Subarnarekha bridge and then we get the answer.
