Answer:
   £42
Step-by-step explanation:
The ratio of Richard's amount to Stephen's amount is ...
   R : S = 3 : 1
The ratio of Natasha's amount to Richard's amount is ...
   N : R = 2 : 1 = 6 : 3
Then the ratio of all three amounts is ...
   N : R : S = 6 : 3 : 1
The proportion of the total that Natasha gets is ...
   6/(6+3+1) = 6/10
so she gets ...
   (6/10)×£70 = £42
Natasha gets £42.
