Step-by-step explanation:
Total no. of questions = 20
Marks given for a correct answer = 4
Marks deducted for a wrong answer = 1
No. of questions attended by the candidate = a
No. of questions the candidate gets correct = c
No. of questions the candidate gets wrong = a - c
Marks obtained for correct answers = 4c
Marks deducted for wrong answers = 1 (a - c)
Total marks scored by the candidate =
Marks obtained for correct answers - Marks deducted for wrong answers
Total marks scored by the candidate = 4c - 1 (a - c)
= 4c - a + c
= 5c - a
Answer:
88.375
Step-by-step explanation:
70 x 0.0825
70 x 0.18
70 + ^
Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.
Answer:
Step-by-step explanation:
Divide 4378 by 15
From 4378 lets take the first two digits for division:
43/ 15
We know that 43 does not come in table of 15
So we will take 15 *2 = 30
43-30 = 13
The quotient is 3 and the remainder is 13
Now take one more number which is 7 with 13
137/15.
Now 137 does not come in table of 15
15*9 = 135
135-137 = 2
It means quotient is 9 and remainder is 2
Now take one more number which is 8 with 2
28/15
28 does not come in table of 15
15*1 = 15
28-15 = 13/15
Now the quotient is 1 and remainder is 13
Hence, the quotient of 4,378 is 291 and remainder is 13 ....
