Ans: C

Failed in 1^st subject = $$(35 / {100} × 2500)$$ = 875.

Failed in 2^nd subject = $$(42 / {100} × 2500)$$ = 1050.

Failed in both = $$(15 / {100} × 2500)$$ = 375.

Failed in 1^st subject only = (875- 375) = 500.

Failed in 2^nd subject only = (1050 – 375) = 675.

Passed in 2^nd only + Passed in 1^st only = (675 + 500) = 1175.
