The remainder can never be negative.

Hence First add 7 to -17, becomes -10, again add 7 to -10 becomes -3. again adding 7 to -3 gives 4 as the remainder
And 7 is added 3 times. hence quotient is -3 and remainder 4.

When -17 is divided by 7, the quotient and remainder are :
a. -3 & 4
b. -2 & 3
c. 4 & -3
d. -3 & -2
e. 2 & -3

Quotient = 7* Divisor + remainder
-17 = 7(divisor) + remainder
0r, -17= 7*-3 + 4

so A fits the bill

Clearly Answer Is a)-3 and 4
because when -17 is dived by 7
we will take -3 as quotient then we will get +4 as remainder

The best way to do this type of question is to analyze the following statement:

A= pQ + R
where Q is the quotient and R is the remainder

We know that A=-17
And P=7

SO any number that fits in the equation is the answer.

ONly Option A satisfies the equation.
7*3+(-4)=17

Since the remainder can be negative, the positive one can be (3).

$$7*(-3)= -21$$ (Hence quotient is -3)

$$-17-(-21)= +4$$(Hence remainder is +4)

N= q.m + r

-17 = -3*7 + 4 where m is the divisor, q = quotient, r = remainder and N is the dividend.
Hence the answer is -3 and 4 option A
