The ratio of ‘metal 1’ and ‘metal 2’ in alloy ‘A’ is 3 :4.Therefore, we can say that 14 kg of alloy 'A' will contain

714

=6
kg of 'metal 1' and

4

714

=8 kg of 'metal 2'.
The ratio of ‘metal 1’ and ‘metal 2’ in alloy ‘B’ is 5 :8.Therefore, we can say that 26 kg of alloy 'B' will contain

5

1326

=10kg of 'metal 1' and

8

1326

=16 kg of metal 2'
Hence, total weight of 'metal 1' in the new alloy =6+10=16kg
Total weight of 'metal 2' in the new alloy =8+16=24kg
Therefore, the ratio of ‘metal 1’ and ‘metal 2’ in the new alloy. =16:24=2:3. Hence, option C is the correct answer.
