1) answer is 'C'
here we get 2 equations
RC = 70 ---- (1)
(R-2)(C+4) = 70 ---- (2)
solving (1) & (2) we get R = 7 & C = 10
2) answer is C. Here,
5/6 (Ponies) = (Ponies having shoe horses) ---- (1)
(Ponies having shoe horses) / 2 = (Icelandic Ponies) ---- (2)
solving (1) & (2) we get,
(Icelandic Ponies) = 5 (Ponies) / 12 ---- (3)
Hence, The total number of ponies has to be divided 12
looking at the choices we get Ponies to be equals to C & E.
But we have to select the minimum as asked by the questions, hence answer is C
