RD Sharma Chapter 3: Pairs of Linear Equations in Two Variables Exercise 3.7 Solutions
The sum of two numbers is 8 . If their sum is four times their difference, find the number. Watch Solution
The sum of digits of a two digit number is 13 . If the number is subtracted from the one obtained by interchanging the digits, the result is 45 . What is the number? Watch Solution
The sum of two-digit number and the number formed by reversing the order of digits is 66 .If the two digits differ by 2, find the number. How many such numbers are there? Watch Solution
The sum of two numbers is 1000 and the difference between their squares is 256000 . Find the numbers. Watch Solution
The sum of a two digit number and the number obtained by reversing the order of its digits is 99 . If the digits differ by 3, find the number. Watch Solution
The sum of digits of a two digit number is 15 . The number obtained by reversing the order of digits of the given number exceeds the given number by 9 . Find the given number. Watch Solution
A number consists of two digits whose sum is five. When the digits are reversed, the number becomes greater by nine. Find the number. Watch Solution
A two-digit number is 4 times the sum of its digits. If 18 is added to the number, the digits are reversed. Find the number. Watch Solution
A two-digit number is 3 more than 4 times the sum of its digits. If 18 is added to the number, the digits are reversed. Find the number. Watch Solution
A two-digit number is 4 more than 6 times the sum of its digits. If 18 is subtracted from the number, the digits are reversed. Find the number. Watch Solution
A two-digit number is 4 times the sum of its digits and twice the product of the digits. Find the number. Watch Solution
A two-digit number is such that the product of its digits is 20 . If 9 is added to the number, the digits interchange their places. Find the number. Watch Solution
The difference between two numbers is 26 and one number is three times the other. Find them. Watch Solution
The sum of the digits of a two-digit number is 9 . Also, nine times this number is twice the number obtained by reversing the order of the digits. Find the number. Watch Solution
Seven times a two-digit number is equal to four times the number obtained by reversing the digits. If the difference between the digits is 3 . Find the number. Watch Solution
Two numbers are in the ratio 5 : 6. If 8 is subtracted from each of the numbers the ratio is 4 : 5. Find the numbers Watch Solution
A Two digit number can be obtained by either multiplying the sum of the digits by 8 and then subtracting 5 or by multiplying the difference of the digit by 16 and then adding 3. Find the number. Watch Solution
