D) 3000
E) 7000
Correct Answer: C
Solution :
Let the total number of candidates who secured qualifying marks in IBPS PO be\[x\]. 15 % of\[x\times \frac{6}{7}-15%\,\,\text{of}\,\,x\times \frac{3}{10}=234\] or,\[\frac{90x}{700}-\frac{45x}{1000}=234\] or\[\frac{900x-315x}{7000}=234\] or,\[585x=234\times 7000\] \[\therefore \]\[x=\frac{234\times 7000}{585}=2800\]
