Cross-multiplying:
45 = 9x
x = 45/9
x = 5

اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Total parts = 2 + 1 = 3
Value of 1 part = 300 ÷ 3 = 100
A’s share = 2 parts = 2 × 100 = 200
B’s share = 1 part = 1 × 100 = 100
200 : 100

- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
B's 1 day work = 1/20
C's 1 day work = 1/30
(B+C)'s 1 day work = 1/20 + 1/30 = 1/12
(B+C)'s 2 days work = 2 × 1/12 = 1/6
Remaining work = 1 - 1/6 = 5/6
A's 1 day work = 1/18
Time taken by A to complete 5/6 work:
= (5/6) / (1/18)
= 5/6 × 18
= 15 days
