Answers and Solution:
1.  (B)
Work done by A and B = 3/5
work done by C = 1-3/5 = 2/5
Amount paid to C = 30000*2/5 = 12000
2.  (D)
3.  (A)
Required number is
= HCF of 24,15 and 18
= 3
4.  (B)
Greatest number that will divide 148,246 and 322 leaving remainders 4,6 and 10 respectively
= HCF of 144,240 and 312
= 24
5.  (A)
6.  (D)
7.  (A)
8.  (B)
let marked price = x
discount price - 1/4 x
selling price - x - 1/4 x = 3/4 x
Required ratio = marked price : selling price
= x : 3/4 x
= 4:3
9.  (B)
sale price = 981
tax = 9%
cost price = 981*100/109
= 900
marked price = 981
required discount = 981-900 = 81
10. (B)
Marked price = 95000
= 9500*90/100*(100-x)/100 = 7695
x = 10%
