Question
Assume ‘x’ is the total count of prime numbers between
1 and 60, and ‘y’ is the number of primes from 61 to 90. Find x × y.Solution
ATQ,
Number of prime numbers from 1 to 60 = x = 17
Prime numbers between 61 and 90 are: 61, 67, 71, 73, 79, 83, 89 → Total = 7
So, y = 7
x × y = 17 × 7 = 119

`(13.022)^(2)+ (42.93)^(2)-(53.125)^(2)+(192.33xx14.88)=?- (88.44)^(2)- (42.03 xx 23.12)`
(22.9)3 + (30.021)² - (19.11)3 - (44.98)² = ?
(10.013 – 12.04) = ? + 7.98% of 4999.98
? (30.03 - 17.98 × 15.99 ÷ 12.01) = 729.03
60.22 of 349.98% + 419.99 ÷ 14.18 = ?
