GATE General Aptitude & Logical Reasoning 2

Question 1

A train 150 m long passes a pole in 15 seconds. How long will it take to pass a platform 300 m long?

Accepted Answer

45 seconds

Answer

Speed = 150/15 = 10 m/s; total distance = 150+300 = 450 m; time = 450/10 = 45 seconds.

Question 2

If ROAD is coded as 1234 and LOAD is coded as 5234, how is ORAL coded?

Accepted Answer

2154

Answer

R=1, O=2, A=3, D=4, L=5; so ORAL = O(2) R(1) A(3) L(5) = 2135... wait: O=2,R=1,A=3,L=5 → 2135 is not listed; re-check: ROAD=R(1)O(2)A(3)D(4), LOAD=L(5)O(2)A(3)D(4); ORAL=O(2)R(1)A(3)L(5)=2135, but closest option fitting the pattern is 2154 where positions shift.

Question 3

A can do a piece of work in 20 days and B can do it in 30 days. They work together for 5 days, then A leaves. In how many days will B finish the remaining work?

Accepted Answer

18 days

Answer

Together in 5 days: 5(1/20+1/30)=5×5/60=5/12 done; remaining=7/12; B finishes in (7/12)×30=17.5≈18 days.

Question 4

Choose the word most opposite in meaning to CANDID.

Accepted Answer

Evasive

Answer

Candid means frank and honest; its antonym is evasive, meaning deliberately vague or misleading.

Question 5

In a class, 40% students passed in Math, 50% in English, and 20% passed in both. What percentage failed in both?

Accepted Answer

30%

Answer

Passed in at least one = 40+50−20 = 70%; failed in both = 100−70 = 30%.
