Question

In a classroom , Mathematics teacher is conducting an activity in which 3 students [A,B,C] are taking part . The teacher assigned student A with number 46640 and assumed the numbers of student B and C as x and y respectively. The condition applied in the activity is B should be subtracted from A , such that A becomes a perfect square and C must be added to A to become a perfect square. Answer any 3 of the following questions :-[ 3 x 1 = 3m ] 1. Find the number which will be given to student B a) 415 b) 112 c) 223 d) 91 2. Find the number which will be given to student C a)25 b) 36 c) 16 d) 8 3. What is the square root of the number given to student A after subtracting B from it a) 122 b) 215 c) 225 d) 144 4. What is the square root of the number given to student A after adding C to it a) 298 b)126 c) 153 d) 216

Answer 1

Answer:

B = 415

C = 16

A= 46640

A-B = 46640-415 =46225

√46225= 215

A+C = 46640+16 =46656

√46656 = 216

1. 415

2. 16

3. 126
