Question

Required sum = 15 (400 + 1450)
Required sum = 15 x 1850 = 27750
Thus, a delay of 30 days will cost the contractor of 27750.
22 The digits of a positive integer, having three digits are in A.P. and their sums
umher obtained by reversing the digits is 594 less than the original number. Find the number.
TON Let the digits at ones, tens and hundreds place be (a - d), a and (a +
respectively. Then, the number is
(a + d) x 100 + ax 10 + (a - d) = 111a +99d
The number obtained by reversing the digits is
(a-d) x 100 + ax 10 + (a + d) = 111a - 99d
It is given that the sum of the digits is 15.
(a - d) + a + (a + d) = 15
Also, it is given that the number obtained by reversing the digits is 594 less than the original
number.
111a - 99d = 111a + 99d - 594
3a = 15 and 198d = 594
.

a = 5 and d = 3
So, the number is 111 x 5+ 99 x 3 = 852.​
