Question

A student multiplied 1234 by 67 instead of multiplying by 76. By how much was his answer lesser than the correct answer.and full answer​

Answer 1

Answer:

• His answer was lesser than the correct answer by 11106.

Step-by-step explanation:

Given that:

• A student multiplied 1234 by 67 instead of multiplying by 76.

To Find:

• By how much was his answer lesser than the correct answer.

Let us assume:

• His answer was lesser than the correct answer by x.

Finding the value of x:

According to the question.

⟶ x = (1234 × 76) - (1234 × 67)

⟶ x = 93784 - 82678

⟶ x = 11106

Hence,

• His answer was lesser than the correct answer by 11106.

Answer 2

Given : A student multiplied 1234 by 67 instead of multiplying by 76.

Exigency To Find : By how much was his answer lesser than the correct answer.

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

❍ Let's say that his answer is lesser than the correct answer by b .

⠀⠀⠀⠀⠀⠀$\underline {\boldsymbol{\star\: According \: to \: \: the \: Question \::}}$

⠀⠀⠀⠀⠀━━━ ⠀⠀⠀A student multiplied 1234 by 67 instead of multiplying by 76.

$\qquad \dashrightarrow \sf b\:=\: \bigg( 1234 \: \times \: 76 \bigg) - \bigg( 1234 \:\times \: 67 \: \bigg) \:\\\\ \qquad \dashrightarrow \sf b\:=\: \bigg( 93784 \bigg) - \bigg( 1234 \:\times \: 67 \: \bigg) \:\\\\\qquad \dashrightarrow \sf b\:=\: \bigg( 93784 \bigg) - \bigg( 82678 \: \bigg) \:\\\\\qquad \dashrightarrow \sf b\:=\: 93784 - 82678 \: \:\\\\\qquad \dashrightarrow \sf b\:=\: 11106 \: \:\\\\\qquad \therefore \pmb{\underline{\purple{\:\frak b\:=\: 11106 \: }} }\:\:\bigstar$

⠀⠀⠀⠀⠀⠀▪︎⠀⠀⠀Here b denotes By how much the answer is lesser than the correct answer which is 11106 .

$\therefore \underline { \sf Hence,\: By \: \bf 11106 \:\sf \: the \:answer \:is \:lesser \:than\:the \:correct \:answer \:}$
