@hemant_malhotra Is ans 65?

@hemant_malhotra THE ANS IS WRONG...IT SHOULD BE IN FIBONACCI SERIES

@YashHChaudhari Could you please provide your solution?

@hemant_malhotra said in Quant Boosters  Hemant Malhotra  Set 14:
The sum of the squares of three numbers, x, y and z is 138, while the sum of their products taken two at a time is 131. Their sum is
(a+b+C)^2 = a^2 + b^2 + c^2 + 2(ab +bc +ca) = 20
Hence
None of the above
