document.write( "Aflin has calculated that if she score 95 on her next three test,it will improve her test average to 93.If Aflin has six tests so far this year,what is her current average.\r\n" );
document.write( "Ans:\r\n" );
document.write( "Let her average for the 6 tests till now be x.\r\n" );
document.write( "Average = sum of scores in the 6 tests / 6\r\n" );
document.write( "So the total of her scores in the 6 tests = 6*x\r\n" );
document.write( "If she scores 95 in each of her next 3 tests, the total would become\r\n" );
document.write( "6*x + 95*3 = 6*x + 285\r\n" );
document.write( "and the total number of tests would be 6+3 = 9\r\n" );
document.write( "Her new average would be (New total)/9\r\n" );
document.write( "= \r\n" );
document.write( "Cross multiplying\r\n" );

document.write( "Average of first 6 tests = 92\r\n" );
