We can't figure this one out! From paper 9 in IPS Daily Practice Tests

Numbers related in the same way. Find the missing number in the 3rd group.

15 (50) 10
20 (56) 8
19 (??) 11

Choices : 60, 55, 65, 70, 67

I am sure it's obvious when we are told!!

Thanks in advance for help!

it's 60, add the numbers either side of the brackets and double

I think the answer is 60..
15+10=25x2=50
20+8=28x2=56
19+11=30X2=60
