The answer is 890 Let me use the following notations for the figures S........ Star M........Moon R......Rocket Given: S+R+M = 60..... (1) R+M = 50......... (2) M-S = 20........ (3) substituting value of R+M from (2) to (1) S+50= 60, S=10 Substituting the value of S in (3) M= 30. Substituting value of M in (2) R=30 Therefore, R x R -S= 30x30- 10= 900-10=890

Since M is 30 and M + R = 50 So R is 20 and ans is 390
