Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70
Step-by-step explanation:
- x²+4+3
- x²+x+3x+3
- x(x+1)+3(x+1)
- (x+1)(x+3)

Answer:
60%
Step-by-step explanation:
To find the total pass = 65 * number of student that passed, let it be be represented by P and number of students that failed F
Total pass = 65p
And total fail = 35F
For the total pass and failure will be 53(P+F)
Equating to total pass and total fail
65P +35F = 53( P+ F)
65P+35F = 53P+ 53F
65P-53P =53F-35F
12P=18F
2P= 3F
Hence there are 3 passing scores for every 2 failure scores, hence there are a multiple of 5 scores and the same multiple of 3 passing scores.
3/5 * 100= 60%
