General Science Tips for Railway Group-D and RRB ALP <\/a><\/p>\n

Solutions for\u00a0Railway Exam Maths Questions and Answers:<\/strong><\/span><\/p>\n

Solutions:<\/strong><\/p>\n

1) Answer (A)<\/strong><\/p>\n

SP of 12 books=1800
\nSP=CP + Profit
\nGiven, Profit of 12 books=3CP
\n\u22341800=12CP + 3CP
\n15CP=1800
\nCP=120<\/p>\n

2) Answer (A)<\/strong><\/p>\n

Let x be the principal amount and r be the compound interest.
\nThe amount after first year =$x + xr$
\nthe amount after second year=$(x + xr) +(xr + xr^{2})=x+2xr + xr^{2}=x(1+r)^{2} $=16900 -(1)
\nSimilarly, the amount after third year =$x(1 + r)^{3}$= 17576 -(2)
\ndividing 2 by 1 we get,
\n1+r=1.04
\nr=.04
\nThus the interest is 4%.<\/p>\n

3) Answer (C)<\/strong><\/p>\n

$ P (1 + .05) ^ {3}$ – P= 630.5
\nSolving for P, we get P = 4000<\/p>\n

4) Answer (B)<\/strong><\/p>\n

Let there be x 10 rupee notes in the sum. The number of 5 rupee notes = 80 – x
\nThe sum = 10x + (80 – x)* 5 = 625
\nSo, x = 45<\/p>\n

5) Answer (A)<\/strong><\/p>\n

Let there be x men initially. They were supposed to complete the work in 20 days.
\nWhen 12 men didn’t show up the work was done in 32 days
\nSo, x- 12 men did the work in 32 days
\nBut x-12 men were supposed to take 20x\/ (x-12) days
\nSo, 20 x\/ (x-12) = 32
\nso, x = 32<\/p>\n

6) Answer (A)<\/strong><\/p>\n

Let there be m men originally to work in 60 days
\nIf the men were m + 8, the work would be completed in 50 days.
\n(m+8)\/m = 60\/50
\nSo, m = 40<\/p>\n

7) Answer (B)<\/strong><\/p>\n

2 boys = 1 man
\nSo, 21 men can do work W is 60 days working 7.5 hours per day.
\nto do 2W, 42 men are needed.
\nTo do the job in 50 days, 60 x 42 \/ 50 men are needed.
\nTo do the job working 9 hours a day, 7.5\/9 x 60 x42\/50 men are needed
\n= 42 men
\nWe only have 21 men so, we get 42 extra boys to get the work needed for the 21 extra men.<\/p>\n

8) Answer (A)<\/strong><\/p>\n

Let his monthly salary be x rupees.
\nSo, 5 (x – 1200) + 7 (x-1300) = 2900
\n12x – 6000 – 9100 = 2900
\nSo, x = 18000\/12 = 1500<\/p>\n

9) Answer (C)<\/strong><\/p>\n

Total temperature for Monday, Tuesday, Wednesday and Thursday = 40 x 3 + 45 = 165 C
\nTotal for Tuesday, Wednesday and Thursday = 41 x 3 = 123 C
\nSo, Temperature for Monday = 165 – 123 = 42 C<\/p>\n

10) Answer (B)<\/strong><\/p>\n

Let the first number be 3x. Second number is 6x. Third number is 2x.
\nSo average = (2x + 3x + 6x)\/3 = 11x\/3
\nBut 11x\/3 = 44
\nSo, x = 12
\n6x = 72<\/p>\n
